Neurological complications of alcohol usage.

The relationships between alcohol usage and a number of neurological syndromes are reviewed. These are often complex and incompletely understood. Multiple rather than single factors are the rule rather than the exception. The correct diagnosis may be missed particularly where the aetiological role of alcohol is overlooked. Multiple diagnoses are not uncommon. Issues of differential diagnosis and diagnostic procedures are discussed. Management, including a number of its pitfalls, is outlined.
