Dear Ms.
Hsiang:
In response to your inquiry about the three categories of diseases, here are the brief explanations:
1.
Organic Mental Disorders: These refer to mental health conditions caused by identifiable physiological factors or medical illnesses.
For example, patients with thyroid disorders often experience symptoms of depression or irritability.
Individuals who have suffered a stroke may develop dementia, memory loss, or depression due to brain damage.
Long-term substance abusers (primarily of amphetamines or inhalants) or alcoholics may experience brain changes leading to psychiatric symptoms such as hallucinations and delusions.
2.
Affective Disorders: These are mental health conditions primarily characterized by emotional disturbances.
The main types include depression (which can encompass major depressive disorder and mild depression) and bipolar disorder (characterized by alternating episodes of mania and depression).
Symptoms of depression include persistent low mood, crying spells, irritability, difficulty concentrating, memory issues, impatience, frequent complaints of physical discomfort (such as headaches and chest tightness), insomnia, and poor appetite.
In contrast, during manic episodes, individuals may exhibit elevated mood, hyperactivity, euphoria, or irritability, talk excessively and rapidly, jump from topic to topic, feel an inflated sense of self-worth, and engage in impulsive behaviors such as excessive spending or neglecting sleep and nutrition.
3.
Neurotic Disorders: It seems there may be a misunderstanding with the term you used; I assume you meant "neurotic disorders"? Neurotic disorders, also referred to as mild mental disorders, are characterized by anxiety as the core issue.
Common types include:
1.
Phobias: Intense fear of specific objects or situations, such as fear of snakes, heights, water, or flying.
2.
Panic Disorder: Experiencing sudden, intense fear without a specific trigger.
3.
Obsessive-Compulsive Disorder (OCD): Characterized by repetitive behaviors driven by internal anxiety or fear, such as excessive handwashing or checking locks and appliances.
4.
Generalized Anxiety Disorder: Persistent feelings of anxiety that lead to physical symptoms such as sweating, gastrointestinal issues (diarrhea or constipation), trembling, palpitations, and muscle tension or pain.
Due to space limitations, I cannot provide a detailed response.
I encourage you to visit the "Taiwan e-Academy" website of the Department of Health's Hospital Management Committee for more information.
Wishing you peace and joy!

Understanding the differences between organic, affective, and functional psychoses is crucial for both diagnosis and treatment in the field of psychiatry. Each category represents a distinct set of symptoms, underlying causes, and treatment approaches.
1. Organic Psychosis:
Organic psychosis refers to mental disorders that are caused by identifiable physical changes in the brain or body. This can include conditions such as traumatic brain injury, infections (like encephalitis), substance abuse, or neurological diseases (such as Alzheimer's or Parkinson's disease). The symptoms of organic psychosis can include confusion, memory loss, hallucinations, and delusions. Because the underlying cause is biological, treatment often focuses on addressing the physical health issues, which may involve medication, rehabilitation, or other medical interventions.
2. Affective Psychosis:
Affective psychosis, often referred to as mood disorders, includes conditions where mood disturbances are prominent. The most common examples are major depressive disorder with psychotic features and bipolar disorder with psychotic features. In these cases, the psychotic symptoms (such as hallucinations or delusions) are directly related to the individual's mood state. For instance, during a depressive episode, a person may experience delusions of worthlessness or guilt, while during a manic episode, they may have grandiose delusions. Treatment typically involves mood stabilizers, antidepressants, and psychotherapy, focusing on stabilizing the mood and addressing the psychotic symptoms.

3. Functional Psychosis:
Functional psychosis, often referred to as schizophrenia or schizoaffective disorder, is characterized by psychotic symptoms that are not attributable to any identifiable organic cause. Individuals with functional psychosis may experience hallucinations, delusions, disorganized thinking, and impaired functioning. Unlike affective psychosis, the mood symptoms may not be as prominent or may occur independently of the psychotic symptoms. Treatment for functional psychosis usually involves antipsychotic medications and psychosocial interventions, focusing on managing symptoms and improving quality of life.

Key Differences:
- Etiology: Organic psychosis has a clear physical cause, while affective psychosis is linked to mood disorders, and functional psychosis has no identifiable organic cause.

- Symptoms: Organic psychosis may present with cognitive deficits and confusion, affective psychosis is characterized by mood disturbances alongside psychotic symptoms, and functional psychosis primarily involves psychotic symptoms without a mood disorder.

- Treatment Approaches: Treatment for organic psychosis focuses on the underlying medical condition, affective psychosis treatment centers on mood stabilization, and functional psychosis treatment involves managing psychotic symptoms with antipsychotic medications.

Understanding these distinctions is essential for effective diagnosis and treatment. If you or someone you know is experiencing symptoms of any of these conditions, it is crucial to seek help from a qualified mental health professional who can provide a comprehensive evaluation and appropriate treatment plan. Mental health is a complex field, and each individual's experience can vary widely, making personalized care essential.
