60 years old alcoholic male presented with urinary incontinence and abnormal gait since 3 months. He also complains of loss of memory. What is the diagnosis?
**Core Concept**
Alcoholism can lead to a range of neurological complications, including damage to the cerebellum and cerebral cortex. This damage can result in ataxia, cognitive impairment, and other neurological symptoms.
**Why the Correct Answer is Right**
The patient's symptoms, including abnormal gait, urinary incontinence, and loss of memory, suggest a diagnosis of Wernicke's encephalopathy. This condition is caused by a deficiency of thiamine (Vitamin B1), which is often seen in chronic alcoholics. The cerebellar ataxia is thought to result from damage to the cerebellar Purkinje cells, while the cognitive impairment is related to damage to the mammillary bodies and other structures in the diencephalon.
