Which is not a mental disorder?

Options

A. Gout
B. Epilepsy
C. Neurosis
D. Psychosis

Answer

To determine which option is not a mental disorder, we can analyze each option provided:

1. **Gout**: Gout is an inflammatory condition that affects the joints, specifically caused by the accumulation of uric acid crystals. It is classified as a type of arthritis and is characterized by swelling and pain in the affected joints. Since gout is a physical health condition and not related to mental health, it is not considered a mental disorder.

2. **Epilepsy**: Epilepsy is a neurological disorder that affects the central nervous system, characterized by recurrent seizures due to abnormal electrical activity in the brain. While it can have psychological effects, epilepsy itself is not classified as a mental disorder.

3. **Neurosis**: Neurosis is a term used to describe a range of mental health conditions that involve anxiety, depression, and other emotional disturbances. Individuals with neurosis may have difficulty coping with stress and may experience symptoms that affect their daily functioning. Therefore, neurosis is indeed a mental disorder.

4. **Psychosis**: Psychosis is a severe mental disorder characterized by a disconnection from reality, which can include hallucinations and delusions. Individuals with psychosis may not be aware of their condition and often require treatment. Thus, psychosis is also classified as a mental disorder.
