Alzheimer’s Disease: A progressive neurodegenerative disease that affects memory, thinking, and behavior.
Stroke: A sudden interruption of blood flow to the brain, which can lead to brain damage and altered mental status.
Epilepsy: A chronic disorder characterized by recurrent, unprovoked seizures.
Multiple Sclerosis: An autoimmune disease that affects the central nervous system, leading to a variety of symptoms, including altered mental status.

2. Infections

Infections can also cause altered mental status, as they can affect the brain and central nervous system. Some common infectious causes include:

Encephalitis: Inflammation of the brain, often caused by a viral infection.
Bacterial Meningitis: An infection of the protective membranes covering the brain and spinal cord.
Brain Abscess: A collection of pus in the brain, usually caused by a bacterial or fungal infection.

In conclusion, altered mental status can be caused by a wide range of illnesses, from neurological disorders and infections to metabolic disorders and toxic exposure. Recognizing the signs and symptoms of altered mental status is crucial, as prompt medical attention can help prevent further complications and improve outcomes.
