Encephalopathy is a broad term used to describe any disease that affects the brain. It can be caused by a variety of factors, including infections, toxins, metabolic disorders, and genetic defects. Encephalopathy can range in severity from mild to severe, and it can be either temporary or permanent.

Definition of Encephalopathy

Encephalopathy is a general term used to describe any disease that affects the brain. The word "encephalopathy" comes from the Greek words "enkephalos," meaning "brain," and "pathos," meaning "suffering." Encephalopathy can be caused by a variety of factors and can have a wide range of symptoms.

• Genetic defects (such as Tay-Sachs disease and Lesch-Nyhan syndrome)
• Head injuries
• Brain tumors
• Stroke
• Hypoxia (lack of oxygen to the brain)

Diagnosis

Encephalopathy is diagnosed based on a physical examination, a medical history, and a variety of tests, including:

• Imaging tests (such as MRI and CT scans)
• Electroencephalography (EEG)
• Lumbar puncture (spinal tap)
