Definition

Altered mental status refers to a change in cognitive function or consciousness that can manifest as confusion, disorientation, decreased alertness, or other cognitive impairments. The term "unspecified" indicates that the exact nature or cause of the altered mental status has not been determined at the time of diagnosis[2][6].

Symptoms

Patients with altered mental status may present with a variety of symptoms, including:
- Confusion or disorientation
- Difficulty concentrating or following conversations
- Memory disturbances
- Changes in alertness (e.g., lethargy or hyperactivity)
- Hallucinations or delusions in some cases

These symptoms can vary widely in severity and may fluctuate over time, depending on the underlying cause.

Potential Causes

Altered mental status can arise from numerous medical conditions, including but not limited to:
- Metabolic disturbances: Such as hypoglycemia, hyperglycemia, or electrolyte imbalances.
- Neurological conditions: Including stroke, seizures, or infections like meningitis or encephalitis.
- Psychiatric disorders: Such as delirium, dementia, or acute psychosis.
