Schizophrenia

Schizophrenia is recognized as the primary psychotic disorder.
It encompasses bizarre thoughts, perceptions, emotions, movements, etc.
Typical onset is in adolescence or early adulthood; for males: late teens to early twenties, for females: twenties to thirties.

Symptoms of schizophrenia can be categorized into two sets: positive and negative symptoms.

Positive symptoms are characterized by the addition of abnormal thoughts and behaviors to the person's life.
- Delusions: Strongly held false beliefs, such as paranoia (persecutory delusions) or grandiosity.
- Hallucinations: Perception-like experiences without an external stimulus.
- Disorganized Thinking and Speech: Includes disorganized behavior, tangential or circumstantial speech, which may include associative looseness or flight of ideas.

Negative symptoms denote the absence or reduction of normal emotional responses or behaviors.
- Symptoms include flat affect, lack of motivation (apathy), social withdrawal, and neglect of personal hygiene.
Negative symptoms often persist even with treatment and are harder to manage than positive symptoms.

Symptoms can emerge abruptly or insidiously; often, negative symptoms are noted first.
There is often a delay in diagnosis until positive symptoms appear, which are definitive for schizophrenia.
Relapse is common due to medications' side effects leading to noncompliance; substance misuse can exacerbate symptoms.
Individuals may also experience developmental delays, complicating their illness.
Schizophrenia is associated with chronic functional impairments, often requiring long-term care or housing facilities.

Treatment includes medications, primarily antipsychotics targeting positive symptoms, with limited effect on negative symptoms.
The prognosis varies: 10-15% of patients may fully recover, while others show improvement but may not achieve independence.
Patients often continue to experience long-term impairments in social and occupational functioning.
Stigmatization and lack of support exacerbate the challenges faced by those with schizophrenia.

Medication: Antipsychotics are the cornerstone of managing schizophrenia, particularly first episode psychosis clinics for early intervention.
Psychosocial interventions: Psychotherapy, social skills training, and cognitive behavioral therapy focus on improved quality of life.
Psychosocial support: Family involvement is crucial in supporting treatment compliance and aiding in socialization.

Schizoaffective disorder includes both mood and psychotic symptoms, possibly showing an easier management curve compared to schizophrenia.
Catatonia is characterized by marked psychomotor disturbance, manifesting as immobility or excessive movement.

Echolalia: Unsolicited repetition of words or phrases, often found in patients with excessive motor activity.
Echopraxia: Involuntary imitation of another's movements or gestures.

Neuroimaging reveals brain structure abnormalities including cortical atrophy, particularly in the frontal lobes, linked with executive dysfunction.
Neurotransmitter dysregulation (dopamine, serotonin, glutamate) is implicated in the pathology of schizophrenia.
Genetic studies highlight significant familial risk factors; individuals with a parent who has schizophrenia have an increased likelihood of developing the disorder.

Environmental factors (urban living, socioeconomic factors) and potential prenatal influences (viral infections during pregnancy) are considered contributing factors to the development of schizophrenia.

The DSM-5 discusses cultural concepts of distress, which must be assessed within their cultural context.
Approaches to treatment must consider diverse manifestations of psychological distress and medication response variations.

When treating individuals with schizophrenia, it is essential to maintain clear communication, avoid confrontation regarding delusions, and facilitate a supportive and empathetic environment.
Monitoring for signs of improvement or deterioration in patients, particularly when engaging in therapy, is critical in managing this complex disorder.
