#### Causes

- Psychiatric conditions (e.g., schizophrenia)
- Substance use or withdrawal (e.g., alcohol, certain drugs)
- Medical conditions (e.g., Charles Bonnet syndrome)
- Sleep-related disturbances (e.g., severe sleep deprivation)

#### Risk Factors
- Advanced age
- Pre-existing neurological or psychiatric conditions
- Substance abuse history
- Chronic sleep deprivation 
- Isolation or sensory deprivation

#### Symptoms
- Seeing patterns, lights, or shapes
- Imagining seeing people or creatures
- Perceiving movement or shadowy figures
- Disturbed spatial perception

#### Diagnosis
- Clinical evaluation and history assessment
- Neurological exam
- Psychiatric evaluation
- Brain imaging (e.g., MRI, CT scan)
- Rule out substance-related causes

#### Treatment Options
- Addressing underlying causes or disorders (e.g., medication adjustments for Parkinson’s disease)
- Antipsychotic medications for psychiatric-related hallucinations
- Cognitive behavioral therapy (CBT)
- Vision aids for those with vision loss-related causes

#### Prognosis and Follow-Up
- Progresses based on underlying cause; may improve with treatment 
- Regular follow-ups to monitor treatment efficacy and adjust as necessary
- Continuous mental health evaluation

#### Complications
- Emotional distress or stress
- Increased risk of accidents

- Potential relationship disturbances

#### Lifestyle & Prevention
- Maintain regular sleep patterns
- Avoid substance use or undergo supervised withdrawal
- Engage in social activities to mitigate isolation

#### Additional Resources
- National Institute of Mental Health (NIMH)
- Alzheimer’s Association for dementia-related hallucinations
- Substance Abuse and Mental Health Services Administration (SAMHSA)

#### Tips for Medical Coders
- Ensure correlation with relevant underlying conditions
- Verify accurate patient history for precise coding
