Schizophrenia Spectrum and Other Psychotic Disorders
According to the DSM-5 diagnostic criteria, to be diagnosed with schizophrenia, an individual must exhibit two or more symptoms of the disorder continuously for at least one month.
One of the required symptoms for a diagnosis of schizophrenia, as per DSM-5 criteria, must include:
1. Delusions: Firmly held beliefs that do not align with reality.
2. Hallucinations: Perceiving things through the senses that aren't actually present, such as hearing voices.
3. Disorganized speech: Communication that is jumbled or incomprehensible.
​
The second symptom can be one of the following:
1. Grossly disorganized or catatonic behavior: Unusual behaviors, confusion, or peculiar movements.
2. Negative symptoms: Reduction or absence of normal functioning, such as lack of emotion, motivation, or ability to plan and carry out tasks.
These symptoms must persist for at least one month, causing significant disruption in social or occupational functioning.
Diagnosis of schizophrenia also requires significant impairments in social or occupational functioning for at least six months. The condition typically begins to manifest in the late teens or early 20s, with men often showing symptoms earlier than women. Early signs may include decreased motivation, strained relationships, and academic difficulties.
According to the National Institute of Mental Health, multiple factors contribute to the development of schizophrenia, including genetics, brain chemistry, environmental influences, and substance use.
​
Although there is no cure for schizophrenia, various treatments can effectively manage its symptoms. Treatment approaches commonly involve:
- Antipsychotic medications: Medications that help alleviate symptoms like delusions and hallucinations.
- Psychotherapy: Talk therapy aimed at enhancing coping skills, managing stress, and improving social interactions.
- Self-management strategies: Techniques to help individuals monitor and cope with symptoms.
- Education: Learning about the illness and its management.
- Social support: Assistance from family, friends, and support groups to enhance quality of life.
These interventions can significantly improve outcomes and help individuals with schizophrenia lead fulfilling lives.
Obsessive-Compulsive and Related Disorders
In the DSM-5, to diagnose obsessive-compulsive disorder (OCD), individuals must experience either obsessions, compulsions, or both.
Obsessions:
-
These are persistent thoughts, urges, or impulses that cause distress or anxiety.
-
They are not simply excessive worries about real-life problems.
-
Examples include fears of contamination, doubts about safety, or a need for symmetry.
Compulsions:
-
These are repetitive behaviors (ex. washing, checking) or mental acts (ex. counting, praying).
-
The behaviors are performed to reduce anxiety or prevent a feared outcome.
-
They are not connected in a realistic way with what they are meant to neutralize or prevent or are clearly excessive.
Diagnosis of OCD requires that these obsessions or compulsions consume a lot of time (at least one hour per day) or cause significant distress or impairment in daily functioning.
Other criteria:
-
Symptoms should not be due to another medical condition or substance use.
-
They should not be better explained by another psychiatric condition, such as generalized anxiety disorder.
​
Treatment:
-
Cognitive-behavioral therapy (CBT), especially exposure and response prevention (ERP), is the primary therapy.
-
Antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs) like Anafranil (clomipramine) or Prozac (fluoxetine), are commonly prescribed to manage symptoms.
Effective treatment typically involves a combination of therapy and medication tailored to the individual's needs and response to treatment.
Personality Disorders
Personality disorders are characterized by enduring patterns of thoughts, feelings, and behaviors that deviate markedly from cultural expectations. These patterns cause significant distress or impairment in social, occupational, or other important areas of functioning.
​
​
Types of personality disorders include:
1. Antisocial Personality Disorder
Antisocial personality disorder is marked by a chronic disregard for rules, social norms, and the rights of others. Symptoms often manifest early in childhood or adolescence and persist into adulthood. Individuals with this disorder frequently struggle to empathize with others and show little remorse for their actions, which may include deceitfulness, impulsivity, aggression, and irresponsibility.
2. Avoidant Personality Disorder
Avoidant personality disorder is characterized by pervasive feelings of inadequacy, extreme sensitivity to criticism or rejection, and a strong desire to avoid social interactions and situations. Individuals with this disorder often experience intense anxiety in social settings, which can lead to avoidance of relationships, work, school, and other activities. This fear of negative evaluation and humiliation can severely impact their daily functioning and overall quality of life.
3. Borderline Personality Disorder
Borderline personality disorder (BPD) involves unstable emotions, relationships, and self-image. People with BPD often experience intense mood swings, fear of abandonment, and impulsive behaviors like reckless driving or self-harm. Treatment usually includes therapy to improve emotional stability and coping skills.
4. Dependant Personality Disorder
Dependent personality disorder (DPD) is when someone constantly worries about being alone and relies heavily on others for support. They often do things to get others to take care of them. Treatment usually focuses on boosting their confidence and helping them make decisions on their own.
​
5. Histrionic Personality Disorder
Histrionic personality disorder involves dramatic emotions and behavior, seeking attention constantly. They feel uneasy when not the center of attention, have fast-changing feelings, and might act in ways that grab attention, even if it's inappropriate.
6. Narcissistic Personality Disorder
Narcissistic personality disorder shows a long-term pattern of self-centeredness, an inflated self-image, and a lack of empathy. People with this disorder focus more on themselves than on others.
​
7. Obsessive-Compulsive Personality Disorder
Obsessive-compulsive personality disorder involves a consistent focus on orderliness, perfectionism, and control, both mentally and interpersonally. It's distinct from obsessive-compulsive disorder (OCD).
8. Paranoid Personality Disorder
Paranoid personality disorder involves a pervasive distrust of others, including close relationships, where individuals often perceive others' motives as malicious without factual basis.
9. Schizoid Personality Disorder
Schizoid personality disorder is characterized by detachment from social relationships, a preference for solitude, emotional coldness, and limited expression of emotions. Individuals with this disorder tend to be more focused on their internal thoughts and experiences than on forming connections with others.
10. Schizotypal Personality Disorder
Schizotypal personality disorder involves odd behaviors, beliefs, and thoughts. People with this condition may have unusual beliefs or strange thinking patterns and find it hard to connect with others.
