Answer 1

To provide a meaningful response, it's important to specify a particular clinical condition or disorder for which you would like an overview involving the details you listed (presenting problem, clinical description, prevalence, incidence, onset, prognosis, and aetiology). Here are the elements you requested structured into an example framework for a common clinical condition: **Major Depressive Disorder (MDD)**.

### 1. Presenting Problem
Patients with Major Depressive Disorder often present with persistent feelings of sadness, loss of interest or pleasure in activities, changes in appetite or weight, sleep disturbances, fatigue, feelings of worthlessness or excessive guilt, and difficulty concentrating. In severe cases, individuals may express thoughts of death or suicide.

### 2. Clinical Description
Major Depressive Disorder is characterized by one or more major depressive episodes, which last at least two weeks. The symptoms must represent a change from previous functioning and must be severe enough to cause significant distress or impairment in social, occupational, or other important areas of functioning. Diagnosis is made based on clinical assessment, often using standardized criteria such as the DSM-5.

### 3. Prevalence
The lifetime prevalence of Major Depressive Disorder in the general population is estimated to be around 15-20%. The 12-month prevalence is about 7-10%, making it one of the most common mental health disorders.

### 4. Incidence
The incidence of Major Depressive Disorder can vary by demographic factors, but it is generally estimated to be around 1-2% per year in the adult population. The incidence rate may increase in specific populations, such as adolescents and young adults, reaching as high as 3-5%.

### 5. Onset
The onset of Major Depressive Disorder can occur at any age, but it most commonly first appears in late adolescence to mid-20s. Early onset (before age 18) is associated with a more chronic and recurring course of the disorder. The onset can be gradual or triggered by specific life events or stressors.

### 6. Prognosis
The prognosis for individuals with Major Depressive Disorder can vary widely. About 50-60% of patients respond to initial treatment, and many experience significant improvement within months. However, chronic depression can lead to increased risk for recurrent episodes, comorbid illnesses, and impaired functioning. Factors such as early intervention, social support, and treatment adherence can positively influence prognosis.

### 7. Aetiology
The aetiology of Major Depressive Disorder is multifactorial and includes a combination of genetic, biological, environmental, and psychological factors. Neurotransmitter imbalances, particularly involving serotonin, norepinephrine, and dopamine, are thought to play a significant role. Life stressors, trauma, brain structure and function anomalies, and a family history of depression contribute to an individual's risk.
