Neurological emergencies--diabetes management.

ABSTRACT

Diabetes can affect the nervous system in several ways. Of all the neurological complications of diabetes, peripheral neuropathy is by far the commonest and has been extensively studied. The involvement of central nervous system can be in several forms. The underlying damage may be due to involvement of the large and small cerebral blood vessels as also due to metabolic derangement caused by prolonged hypoglycemia, anoxia or ketoacidosis. The neurological emergencies that occur in diabetes can be 1) atherothrombotic and lacunar strokes; 2) convulsive disorder in the setting of both hypo and hyperglycemia; 3) coma; 4) cranial neuropathies; and 5) acute proximal muscle weakness. In patients with diabetes, atherothrombotic stroke is associated with poor outcome. Hyperglycemia at the time of stroke is an important risk factor for an adverse outcome than chronic stable diabetic state. Proper management of diabetes in these acute situations is crucial for a better outcome of the underlying disease process.
