F04 Amnestic disorder due to known physiological condition

ICD10CM code

#### Name of the Condition
- Common Name: Amnestic Disorder Due to Known Physiological Condition
- Medical Term: Amnestic Disorder, ICD Code: F04

#### Summary
Amnestic disorder due to a known physiological condition is characterized by significant memory loss where the ability to learn new information or recall past experiences is affected. This condition stems from an identifiable physical cause rather than psychological factors.

#### Causes
- Physical damage to the brain due to injury or disease
- Neurological disorders such as Alzheimer's disease
- Alcohol or drug addiction leading to conditions like Wernicke-Korsakoff syndrome
- Hypoxia (lack of oxygen to the brain)

#### Risk Factors
- Advanced age
- Chronic alcohol abuse
- Severe head trauma
- Poorly controlled diabetes
- Stroke or brain infection

#### Symptoms
- Difficulty retaining new information
- Forgetfulness regarding past events
- Disorientation to time and place
- Confabulation (making up stories to fill memory gaps)

#### Diagnosis
- Detailed medical history and physical examination
- Neuropsychological testing to assess memory function
- Imaging tests such as MRI or CT scans to identify brain damage
- Laboratory tests to rule out other causes like nutritional deficiencies

#### Treatment Options
- Cognitive rehabilitation therapy to improve memory skills
- Medications to address underlying causes, such as thiamine supplements for alcohol-related conditions
- Lifestyle modifications to reduce risk factors
- Supportive therapies like counseling and memory aids

#### Prognosis and Follow-Up
- The prognosis varies depending on the cause; some may recover partially with treatment
- Regular follow-ups to monitor progress and adjust treatments as necessary

#### Complications
- Persistent memory deficits affecting daily living
- Increased risk of injury due to disorientation or confusion
- Potential for depression or anxiety due to memory issues

#### Lifestyle & Prevention
- Avoidance of alcohol and harmful substances
- Maintaining a healthy diet and regular exercise to improve overall brain health
- Controlling chronic conditions like hypertension and diabetes

#### When to Seek Professional Help
- Sudden or progressive memory loss
- Severe disorientation or confusion
- Inability to recognize familiar people or places
