Diagnosing a Disorder

From common symptoms, the current edition of Diagnostic and Statistical Manual of Mental Disorders (DSM) describes more than three hundred different disorders. However, these different disorders are arbitrarily defined by a group of professionals who decide which symptoms to group together.

Dr. Randolph Nesse wrote:

“The diagnostic system generates interminable debate—and intense controversy” (Nesse, 2019).

Many sessions leading to releases includes heated discussions over which disorders to include and which ones to exclude.

The DSM resembles a medical encyclopedia for identifying diseases. In many ways, the DSM helped organize a chaotic field of study and treatment. By formulating diagnostic categories of mental disorders to resemble the medical communities’ categories of diseases. Unfortunately, mental states and disorders are a bit different than other diseases. They still exist in the realm of subjective constructions, entirely based on groupings of symptoms.

Nesse explains that they don’t have “specific causes we have been able to identify, such as the bacteria that cause pneumonia. They can’t be diagnosed with blood tests the ways diabetes can. They don’t have definitive tissue abnormalities, such as the dying neurons in multiple sclerosis.”

Nesse emphasizes that mental disorders are defined by “clusters of symptoms.” Each disorder is defined by a list of symptoms. If a person has enough symptoms on the list for long enough, the diagnosis applies (Nesse, 2019). Contrast this with the medical community, a doctor may also use the checklist approach, identifying symptoms. However, after gathering a list of symptoms, they only make a preliminary diagnosis that they can validate through tests such as blood work, brain scans, and tissue samples.

The ICD and the DSM

The equivalent to the DSM in Europe is the ICD (International Classification of Diseases), published by the World Health Organization (WHO). The ICD is a standard diagnostic tool for health management, clinical purposes, and research across the world. A significant differences is that the ICD covers both physical and mental health conditions, while the DSM focuses only on mental disorders (Sanford, 2024).

The ICD and the DSM have some similarities and differences in their structure, content, and criteria. The ICD-11, which will become the official ICD classification system on January 1, 2022, will show more alignment with the DSM-5, the latest edition of the DSM (Mulhauser, 2011). However, there are still some areas of disagreement and controversy between the two systems, such as the classification of personality disorders, autism spectrum disorder, and post-traumatic stress disorder (Frances, 2013).

The DSM is more commonly used in the US and Canada, but it is also utilized in various European countries alongside the ICD. Some psychiatrists may prefer the DSM for its more detailed descriptions, examples, and guidelines, while others may favor the ICD for its more global and diverse perspective.

By recognizing and understanding the real nature of these symptoms, we can work towards providing better support and care for those affected by psychological disorders. This entails delving into the intricate nuances of each individual’s experience, acknowledging the unique ways in which psychological disorders manifest, and tailoring support measures to address these specific needs. It involves fostering empathy, dispelling stigma, and building communities of understanding and acceptance.

Ultimately, this approach can pave the way for comprehensive, person-centered care that not only alleviates symptoms but also nurtures holistic well-being for those grappling with psychological disorders.

Persistent Feelings of Sadness or Hopelessness

Persistent feelings of sadness or hopelessness, also known as persistent depressive disorder or dysthymia, are characterized by a low mood that lasts for an extended period of time, typically for two years or more. Individuals experiencing this symptom may feel constantly down, empty, or hopeless, regardless of the circumstances. This enduring state of sadness can lead to a lack of interest or pleasure in usual activities, changes in appetite or sleep patterns, low energy, and difficulty concentrating. It’s important to seek professional help if you or someone you know is experiencing these persistent feelings to receive appropriate support and treatment.

Psychological Disorders Associated with Persistent Feelings of Sadness or Hopelessness

• Major Depressive Disorder (MDD): Characterized by a prolonged period of sadness or a lack of interest in life activities
• Persistent Depressive Disorder (PDD), also known as dysthymia: A chronic form of depression with long-term symptoms of sadness and hopelessness.

Feelings of Worthlessness or Excessive Guilt

Feelings of worthlessness or excessive guilt are common symptoms of various mental health conditions, such as depression or anxiety disorders. Individuals experiencing these symptoms often have a persistent sense of self-blame, unworthiness, or inadequacy, even when there is no rational cause for such feelings. This can lead to a reduced sense of self-esteem and can be accompanied by negative thoughts and emotions, impacting daily functioning and well-being. It’s important for individuals experiencing these symptoms to seek professional help and support to address these challenging feelings.

Psychological Disorders Associated with Feelings of Worthlessness or Excessive Guilt

Feelings of worthlessness or excessive guilt are commonly associated with several mental health disorders, including:

• Obsessive-Compulsive Disorder (OCD): Guilt is a frequent symptom, especially when linked to intrusive thoughts.
• Post-Traumatic Stress Disorder (PTSD): May include feelings of guilt, particularly survivor’s guilt or guilt over actions taken during traumatic events.

Excessive Fears or Worries

Excessive fears and worries, often referred to as anxiety, are psychological symptoms characterized by persistent and excessive apprehension or concern about everyday situations. Individuals experiencing this symptom may find it challenging to control their worries, even when they recognize that their concerns are exaggerated or irrational. This heightened state of anxiety can lead to physical and emotional manifestations, such as restlessness, fatigue, irritability, muscle tension, and difficulty concentrating. It can significantly impact daily functioning and overall well-being. Professional support and interventions, such as therapy and possibly medication, are often recommended to address excessive fears and worries.

Psychological Disorders Associated with Excessive Fears and Worries

Excessive fears or worries are characteristic symptoms of several psychological disorders, most notably:

• Post-Traumatic Stress Disorder (PTSD): After a traumatic event, individuals may experience intense fear or worry, reliving the event through flashbacks or nightmares.

These disorders can significantly impact an individual’s ability to function and enjoy life, but with proper treatment, people can manage their symptoms effectively.

Impulsivity

Impulsivity is often considered a symptom of various psychological disorders, including attention-deficit/hyperactivity disorder (ADHD), borderline personality disorder, bipolar disorder, and substance use disorders. It is characterized by acting on urges or desires without considering the potential consequences, leading to impulsive behaviors. This can manifest in various ways, such as reckless decision-making, difficulty in delaying gratification, or engaging in risky activities without adequate forethought. Impulsivity can significantly impact an individual’s daily functioning and overall well-being when it is a symptom of a psychological disorder.

See Impulsivity: A Character Trait for more on this symptom

Psychological Disorders Associated with Impulsivity

Impulsivity is a characteristic that can be associated with various mental health disorders. Some of the disorders linked to impulsivity include:

• Attention Deficit Hyperactivity Disorder (ADHD): Characterized by problems with attention, hyperactivity, and impulsiveness.
• Substance-Related Disorders: Impulsivity can be both a cause and a consequence of substance abuse.

• Mood Disorders: Some mood disorders, like bipolar disorder, can involve periods of impulsive behavior during manic or hypomanic episodes.

It’s important to note that impulsivity can vary in presentation and severity, and having impulsive tendencies does not necessarily indicate the presence of a disorder. For a proper diagnosis and treatment, a thorough evaluation by a mental health professional is essential.

Sudden Mood Swings (Emotion Lability)

Sudden mood swings, also known as emotional lability, refer to rapid changes in a person’s emotional state. This can involve shifting from one emotion to another very quickly, often without an obvious trigger or cause. These fluctuations may include going from happiness to sadness, or from calmness to irritability within a short period of time. Sudden mood swings can be associated with various psychological conditions, such as bipolar disorder, borderline personality disorder, or certain types of depression. It can also be a symptom of hormonal changes, stress, or other physiological factors. Understanding and addressing the underlying causes of sudden mood swings is crucial for effective management and treatment.

See Emotional Lability for more on this topic

Psychological Disorders Associated with Emotion Lability

Sudden mood swings can be a symptom of various psychological disorders, including:

• Bipolar Disorder: Characterized by dramatic shifts in mood, energy, and activity levels, ranging from manic highs to depressive lows.

It’s important to note that confusion can also be a symptom of other medical conditions, such as a stroke or a reaction to medication. If confusion is new or has worsened, it’s crucial to consult a healthcare professional for a proper diagnosis and treatment plan.

Difficulties with Concentration

Experiencing difficulties with concentration can manifest as an inability to focus, maintain attention, or stay on task. This may lead to trouble processing information, following conversations, or completing daily activities that require sustained attention. Additionally, it can impact academic or work performance and contribute to feelings of frustration or inadequacy. Difficulty with concentration might also stem from various underlying factors, such as stress, anxiety, depression, attention-deficit hyperactivity disorder (ADHD), or other medical conditions.

• Anxiety Disorders: May lead to changes in sleep patterns, such as difficulty falling asleep or staying asleep, and can affect appetite.
• Eating Disorders: Such as anorexia nervosa, bulimia nervosa, and binge eating disorder, directly involve appetite changes and can also disrupt sleep.

These symptoms can significantly impact daily functioning and quality of life. If you or someone you know is experiencing these symptoms, it’s important to seek professional help for a proper diagnosis and treatment plan.

Fatigue

Fatigue is characterized by a persistent feeling of tiredness, weakness, or exhaustion that can be physical, mental, or both. Individuals experiencing fatigue may have reduced energy levels, find it difficult to concentrate, and may feel a lack of motivation. It can also manifest as muscle weakness, slowed reflexes, and difficulty in performing routine tasks. The sensation of fatigue can vary in intensity and can be a result of various factors such as insufficient rest, overexertion, medical conditions, or psychological stress.

Psychological Disorders Associated with Fatigue

Fatigue is a common symptom that can be associated with a variety of psychological disorders. Here are some possible disorders where fatigue is a prominent feature:

• Major Depressive Disorder (MDD): Fatigue is a frequent symptom of depression, often leaving individuals feeling physically and mentally drained.
• Bipolar Disorder: Both depressive and manic episodes can include fatigue, affecting energy levels and motivation.
• Generalized Anxiety Disorder (GAD): Chronic anxiety can lead to persistent fatigue, impacting daily functioning.
• Attention-Deficit/Hyperactivity Disorder (ADHD): Individuals with ADHD may experience fatigue due to constant mental effort required to focus4.
• Chronic Fatigue Syndrome (CFS): While not solely a psychological disorder, CFS involves severe, unexplained fatigue that isn’t improved by rest and is often worsened by physical or mental activity.

If you’re experiencing fatigue, it’s important to consult with a healthcare professional to explore the underlying causes and appropriate treatment options.

Unexplained Aches and Pains

Unexplained aches and pains, also known as somatic symptom disorder, refers to the presence of physical symptoms that cannot be fully explained by a general medical condition. These symptoms may include headaches, stomach aches, back pain, or other discomfort, and they can cause significant distress or disruption in daily life.

In the context of psychological disorders, unexplained aches and pains are often linked to somatic symptom disorder, where the physical symptoms experienced are either disproportionate to the identified medical condition or have no apparent medical explanation. Individuals with this disorder may become excessively preoccupied with their symptoms, leading to heightened anxiety and impairment in functioning.

It’s important to note that the experience of unexplained aches and pains in connection with a psychological disorder is complex and may involve a combination of biological, psychological, and social factors. Therefore, a comprehensive approach that considers both physical and psychological aspects is necessary for effective management and treatment.

See Psychosomatic Disorder for more on this topic

Psychological Disorders Associated with Unexplained Aches and Pains

Unexplained aches and pains can be associated with several psychological disorders, often as part of psychosomatic symptoms. Here are some disorders that may include these symptoms:

• Depression: Can manifest physical symptoms such as muscle aches, headaches, and fatigue, which may not have a clear physical cause.
• Anxiety Disorders: Including generalized anxiety disorder and panic disorder, can cause muscle tension and pain.
• Somatization Disorder: A condition where psychological distress is expressed through physical symptoms.
• Fibromyalgia: While primarily characterized by widespread pain, it often co-occurs with psychological stress and disorders such as anxiety and depression.
• Chronic Fatigue Syndrome (CFS): Known for severe fatigue, it can also include unexplained muscle and joint pain, and is sometimes linked to psychological factors.

These symptoms are very real and can significantly impact an individual’s quality of life. It’s important to consult with a healthcare professional for a proper diagnosis and treatment plan.

Digestive Issues

Digestive issues, such as irritable bowel syndrome (IBS) or functional dyspepsia, are often closely linked to psychological disorders. The gut-brain axis, a bidirectional communication system between the central nervous system and the enteric nervous system, plays a crucial role in this relationship.

Psychological disorders, such as anxiety, depression, and stress, can exacerbate digestive issues. Conversely, chronic digestive problems can contribute to the development or worsening of psychological disorders. This complex interplay is thought to involve various factors, including the release of stress hormones, changes in gut motility, and altered gut microbiota composition.

Furthermore, individuals with conditions like IBS often report heightened levels of anxiety and depression, indicating the intricate connection between digestive issues and psychological well-being. Understanding and addressing this relationship is essential for providing comprehensive care to individuals dealing with both digestive issues and psychological disorders.

Psychological Disorders Associated with Digestive Issues

Digestive issues can be associated with a range of psychological disorders due to the close connection between the gut and the brain, often referred to as the gut-brain axis. Here are some disorders that have been linked to digestive problems:

• Anxiety Disorders: Generalized anxiety disorder (GAD), social anxiety disorder (SAD), panic disorder, and phobias may all present with gastrointestinal symptoms.
• Depression: This mood disorder can affect gut health, potentially leading to symptoms like stomach pain and changes in bowel habits.
• Post-Traumatic Stress Disorder (PTSD): PTSD can affect gut health and may be associated with conditions like irritable bowel syndrome (IBS).
• Irritable Bowel Syndrome (IBS): While IBS is primarily a digestive condition, it’s often found in individuals with psychiatric comorbidities such as anxiety and depression.

These connections underscore the importance of considering both physical and psychological aspects when addressing digestive symptoms.

Headaches

Headaches can be related to various psychological disorders, such as anxiety, depression, and somatization disorders. Stress and emotional tension can contribute to the onset or exacerbation of headaches. Additionally, individuals with psychological disorders may experience somatic symptoms, including headaches, as a manifestation of their mental health condition. It’s important to consider the psychological and emotional well-being of individuals experiencing chronic or severe headaches, as addressing underlying psychological factors may be an important aspect of their care.

Psychological Disorders Associated with Headaches

Headaches, particularly chronic ones, can be associated with several psychological disorders. Some of the common associations include:

• Depression: Individuals with depression often report headaches, particularly tension-type headaches.
• Anxiety Disorders: There is a strong link between anxiety disorders and headaches, including migraines.
• Bipolar Disorder: People with bipolar disorder, especially Bipolar 2 disorder, frequently experience headaches, particularly migraines.
• Post-Traumatic Stress Disorder (PTSD): Migraines are more common in individuals with PTSD than in the general population.

These disorders can either contribute to the onset of headaches or exacerbate existing headache conditions. It’s important to address both the psychological and physical aspects of headaches for effective management and treatment.

Feeling Overwhelmed

Feeling overwhelmed in connection to psychological disorders can manifest in various ways. Individuals may experience a sense of being unable to cope with their thoughts, emotions, or daily tasks. This can lead to a state of heightened anxiety, panic, or a feeling of being emotionally paralyzed. In some cases, it may also lead to physical symptoms such as racing heart, shortness of breath, or muscle tension. It’s important to note that being overwhelmed can be a common symptom of several psychological disorders, including anxiety disorders, depression, PTSD, and OCD, among others. In such cases, seeking professional help from a mental health professional is crucial in addressing and managing these challenges.

• Depression: Overwhelm can be both a symptom and a cause of depression.
• Anxiety Disorders: People who experience chronic anxiety may often feel overwhelmed.
• Post-Traumatic Stress Disorder (PTSD): Those with PTSD may feel overwhelmed by stressors or triggers related to their trauma.
• Obsessive-Compulsive Disorder (OCD): Individuals with OCD might feel overwhelmed by their compulsions or obsessions.

These conditions can exacerbate the feeling of being overwhelmed, and conversely, feeling overwhelmed can also worsen these psychological disorders. It’s important to seek professional help if feelings of being overwhelmed are persistent and impacting daily life.

Irritability

Heightened Emotional Sensitivity

Heightened emotional sensitivity can be a symptom of various psychological disorders, including but not limited to anxiety disorders, post-traumatic stress disorder (PTSD), borderline personality disorder, and depression. Individuals experiencing heightened emotional sensitivity may react more intensely to emotionally stimulating situations, exhibiting increased vulnerability to stress, mood swings, and difficulty in managing their emotions. This heightened sensitivity can significantly impact their daily functioning and interpersonal relationships. It’s important to note that emotional sensitivity alone is not indicative of a specific psychological disorder, and a comprehensive assessment by a qualified mental health professional is necessary for an accurate diagnosis and appropriate treatment.

See Emotional Sensitivity for more on this topic

Psychological Disorders Associated with Heightened Emotional Sensitivity

Heightened emotional sensitivity can be associated with several psychological conditions. Some of these include:

• Highly Sensitive Person (HSP): This is not a disorder, but a personality trait characterized by deeper cognitive processing of emotions, greater empathy, and increased sensitivity to environmental stimuli.
• Borderline Personality Disorder (BPD): Individuals with BPD may experience intense emotions and heightened sensitivity to perceived rejection or abandonment.
• Autism Spectrum Disorder (ASD): Some individuals with ASD may have heightened responses to sensory experiences and emotions.
• Anxiety Disorders: These can include heightened emotional sensitivity and reactivity.
• Attention-Deficit/Hyperactivity Disorder (ADHD): While ADHD is primarily associated with attention and hyperactivity, it can also involve emotional sensitivity.
• Mood Disorders: Such as depression and bipolar disorder, where individuals may experience heightened emotional sensitivity, especially during mood episodes.

It’s important to note that heightened emotional sensitivity is a broad symptom and can be present in various mental health conditions. A mental health professional can provide a proper diagnosis and treatment plan.

Social Withdrawal

Social withdrawal is a behavioral pattern characterized by a person’s tendency to avoid or minimize social interactions and activities. In the context of psychological disorders, social withdrawal can manifest as a symptom of conditions such as depression, anxiety disorders, schizophrenia, and social anxiety disorder. Individuals experiencing social withdrawal may isolate themselves from social situations, experience reduced interest in activities they once enjoyed, exhibit a lack of motivation to engage with others, and may prefer to spend extended periods alone. This withdrawal can have a significant impact on a person’s functioning and quality of life, and it often necessitates professional intervention and support.

See Social Withdrawal for more on this symptom

Psychological Disorders Associated with Social Withdrawal

Social withdrawal can be a symptom of several psychological disorders, including:

• Anxiety Disorders: Individuals with anxiety may avoid social interactions to prevent feelings of unease or fear.
• Depressive/Mood Disorders: Depression can lead to a lack of interest in social activities and a desire to isolate.
• Personality Disorders: Certain personality disorders may cause individuals to withdraw from social contact.
• Schizophrenia: Those with schizophrenia may experience social withdrawal due to difficulties in processing social cues or paranoia.
• Autism Spectrum Disorders: Children and adolescents with autism may show social withdrawal as they might find social interactions challenging.

These conditions can impact a person’s ability to engage in social interactions and develop relationships. If social withdrawal is affecting one’s life, it’s important to seek professional help.

Decreased Interest in Previously Enjoyed Activities

Decreased interest in previously enjoyed activities, also known as anhedonia, is a common symptom associated with various psychological disorders, particularly depression and schizophrenia. Anhedonia refers to the reduced ability to experience pleasure from activities usually found enjoyable or rewarding. This can include hobbies, social interactions, or other activities that previously elicited positive emotions.

In depression, anhedonia is considered one of the key diagnostic criteria, as it significantly impacts an individual’s quality of life and functioning. It often manifests as a pervasive lack of motivation and engagement in activities that were once meaningful. This symptom can contribute to the overall feeling of emptiness and hopelessness experienced by individuals with depression.

In schizophrenia, anhedonia is also prominent and can further contribute to social withdrawal and impaired functioning. Individuals may struggle to find joy in activities they previously found pleasurable, leading to a decreased desire to participate in social events or engage in hobbies. This symptom can significantly impact their overall well-being and ability to lead a fulfilling life.

Understanding and addressing anhedonia is crucial in the treatment of these psychological disorders. Therapeutic interventions, including psychotherapy and medication, aim to help individuals regain interest in activities and improve their overall quality of life. Additionally, identifying and addressing underlying factors contributing to anhedonia is essential for a comprehensive approach to treatment.

See Anhedonia for more on this symptom

Psychological Disorders Associated with Anhedonia

Anhedonia, the inability to feel pleasure or enjoyment, is commonly associated with several psychological disorders, including:

• Major Depressive Disorder: Often a core symptom, affecting the ability to experience joy.
• Bipolar Disorder: Can occur during depressive phases.
• Schizophrenia: Affects the emotional and motivational aspects of the disorder.
• Substance Use Disorders: Particularly during withdrawal phases.
• Post-Traumatic Stress Disorder (PTSD): Can be a response to trauma-related stimuli.
• Parkinson’s Disease: Although primarily a neurological condition, it has psychiatric manifestations that can include anhedonia.
• Traumatic Brain Injury: Can lead to changes in emotional processing, including anhedonia.

These disorders can affect the brain’s reward system, particularly dopamine pathways, which are crucial for experiencing pleasure. Treatment often involves addressing the underlying condition with therapy, medication, or a combination of both.

It’s important to note that symptoms can vary greatly depending on the specific mental disorder and the individual experiencing them. If you or someone you know is struggling with mental health issues, seeking professional help is crucial for proper diagnosis and support.
