The neurologic complications of alcoholism.

Neurologic complications may appear before the primary disease, alcoholism, is recognized. The common syndromes are polyneuropathy, the withdrawal syndrome and the combination of Wernicke's encephalopathy and Korsakoff's psychosis. Other conspicuous clinical pictures include ataxia of cerebellar origin, convulsions, acute hallucinosis, myopathy and coma. Rarer disorders are Marchiafava-Bignami disease and central pontine myelinolysis.

Impairment ratings for posttraumatic headache.

No standardized criteria are available for establishing impairment ratings for pain or posttraumatic headache. The AMA Guides to the Evaluation of Permanent Impairment, 3rd Edition, 1988, defines impairment as "the loss of use of, or derangement of any body part, system or function." Headaches may be classified under episodic neurological disorders and impairment based loosely on frequency, severity and duration of attacks and how activities of daily living are affected. Other systems base ratings by physical findings or diagnosis. Criteria for posttraumatic headache are proposed in the form of a mnemonic: IMPAIRMENT. Intensity, Medication use, Physical signs/symptoms, Adjustment, Incapacitation, Recreation, Miscellaneous activity of daily living, Employment, Number (frequency), Time (duration of attacks). Each are scored from 0 to 2 points. There are three physician modifiers, scored from 0 to -4 points: Motivation for treatment, Overexaggeration or overconcern, Degree of legal interest. Case examples will illustrate how impairment ratings are determined, along with further details on scoring. Proposed criteria for posttraumatic headache impairment are understandable, easy to utilize and reproducible.

Cognitive symptoms in patients with posttraumatic headache.

A variety of symptoms (postconcussion symptoms) have been consistently reported following mild head or neck injury. One symptom which may have been under reported is cognitive impairment. We conducted a retrospective study of 100 patients presenting for evaluation and treatment of posttraumatic headache at our headache clinic. Sixty-five percent reported difficulties with either memory, concentration, and/or thinking. The most common cognitive symptoms reported were concentration+memory problems, concentration + memory + thinking difficulties, concentration disturbances, and difficulty remembering, respectively. Subjects in both groups (with cognitive symptoms and without cognitive symptoms) were similar in age, but females seemed more predisposed than males to cognitive impairment following mild head injury. It is suggested that clinicians thoroughly evaluate patients for cognitive symptoms, particularly when patients have a permanent condition and are subsequently involved in litigation.
