What should psychiatry residents be taught about neurology?: A survey of psychiatry residency directors.

OBJECTIVES: To improve our ability to teach psychiatry residents during their required 2 months on neurology rotations, we investigated the perceived needs of psychiatry program training directors. METHODS: We contacted the program directors organization of the American Psychiatric Association and disseminated a web-based survey to all program directors. The survey asked questions about the format and content of neurology training desired for psychiatry residents. The survey was sent a second time to increase response rate. RESULTS: Sixty (32%) training directors responded. Overall satisfaction with neurologic education was rated at 3.6 out of 5 (standard deviation +/- 0.96). The specific content areas which elicited the most interest for focused training modules were differential diagnosis and biologic substrates of dementia, evaluation and treatment of drug-related and spontaneous movement disorders, evaluation and management of sleep disorders, cognitive and mood effects of stroke, and inherited disorders. Many program directors commented on perceived weaknesses of inpatient-based exposure to neurology; 78% of responders favored outpatient and consultation settings. CONCLUSIONS: In an era of deliberation about neurobehavioral integration and cross-training of neurologists and psychiatrists, neurologists should strive to provide the best possible multidisciplinary education to psychiatry trainees.

Analysis of the first night effect and sleep parameters in medically refractory epilepsy patients.

OBJECTIVES: To assess the first night effect (FNE) and compare sleep stage proportions to normative values in a sample of medically refractory epilepsy patients. PATIENTS AND METHODS: Sleep parameters of 53 epilepsy patients, ages (18-56, mean: 34+/-12, 25 females 28 men), who underwent two consecutive nights of polysomnography (PSG) were compared. Non-rapid eye movement (NREM) stage 3 and NREM stage 4 were combined as slow wave sleep (SWS). Sleep efficiency, sleep latency, rapid eye movement (REM) latency, number of stage shifts, total minutes and proportion of total sleep time for stage 1, stage 2, SWS, and REM sleep were compared between the 2 nights. RESULTS: SWS was the only parameter that differed between nights 1 and 2 for both total minutes (P=0.02) and proportion of total sleep time (P=0.01), although the means for both nights were within the normative range. Comparing sleep proportions to normative values indicates that our patients had increased NREM stage 1 and decreased REM sleep. CONCLUSIONS: We observed a minimal FNE in this sample of epilepsy patients manifested by reduced SWS. Multiple PSGs to accommodate the FNE may not be necessary in this population.

Seizure disorders in the elderly.

Seizure disorders become increasingly common after the age of 60 years and can have a significant impact on functional status. The goal of antiepileptic drug therapy is to control seizures but preserve quality of life. If possible, seizure control should be achieved with one agent given in the lowest effective dosage. Clinical response, rather than drug levels, should guide dosage changes. All antiepileptic drugs can cause dose-dependent sedation and cognitive impairment. Although the newer agents may have theoretical advantages over standard antiepileptic agents, higher cost may limit their use. Drugs for first-line monotherapy of seizures in elderly patients include carbamazepine, valproic acid, oxcarbazepine, gabapentin, and lamotrigine.

Lessons in mentoring.

Mentoring is an essential catalyst for a successful medical career in science or clinical practice. In recent years, tools have been developed to measure the impact of mentoring on career achievements, and numerous models have been developed to improve mentor training. Sid Gilman, M.D., F.R.C.P., Chair of Neurology for 26 years at the University of Michigan, is well-recognized as a role model for mentors in neurology across the country. We report the result of a survey of his former trainees on the valuable aspects of his mentoring style. A review of the current mentoring literature, including suggested training programs for mentors, is also provided.

Long-term outcome of nonsurgical candidates with medically refractory localization-related epilepsy.

PURPOSE: Epilepsy surgery can result in complete seizure remission rates of upto 80% in patients with mesial temporal sclerosis and unilateral seizures. The seizure-free rate after surgery for patients with extratemporal nonlesional epilepsy has ranged between 30% and 40%. Some patients with medically refractory localization-related epilepsy cannot be offered surgical resection because of inadequate localization of the epileptogenic zone, documentation of bilateral ictal onsets, or functionally important areas of cortex that prohibit resection. The short-term rate of complete remission with medications in temporal lobe epilepsy is poor. Less is known about remission rates in patients who are not surgical candidates. In this study, we evaluated the outcome of medical treatment in patients with medically refractory partial epilepsy who were evaluated for possible epilepsy surgery but deemed to be inadequate surgical candidates. METHODS: A retrospective chart review and telephone survey with a self-rating questionnaire were completed for all patients who underwent epilepsy surgery evaluation but were not ultimately offered surgical treatment at the University of Michigan from 1990 through 1998. We assessed changes in seizure frequency and type, imaging characteristics, ictal recordings, interim medication history, and subjective changes in quality of life. RESULTS: Thirty-four subjects were available for follow-up study, at an average of >4 years after surgical evaluation. A significant reduction in seizure frequency was noted at the time of follow-up compared with that at the time of surgical evaluation. Of patients, 21% achieved seizure remission and remained seizure free for an average of 2.5 years. Four of the seven seizure-free patients attributed their remission to new antiepileptic drugs (AEDs). On a global self-rating item, 15 of 34, or 44%, felt more or much more satisfied with their lives, and 41% felt their quality of life was stable. CONCLUSIONS: A surprisingly large number of patients we surveyed, with refractory partial epilepsy not eligible for surgical management, reported reduced seizure frequency at follow-up, and 21% were seizure free. Our findings suggest that the long-term prognosis in patients with refractory partial epilepsy who are not surgical candidates may be more positive than might be generally expected.

Sodium methohexital (brevital) as an anesthetic in the Wada test.

PURPOSES: We report our experience with sodium methohexital (Brevital) as an anesthetic used in the Wada test for language and memory in 86 epilepsy surgery patients (173 procedures). METHODS: The methods are compared with those of the more commonly used anesthetic sodium amobarbital (Amytal). RESULTS: Despite differences between the methohexital and amobarbital test protocols, the behavioral and neurologic effects of the two anesthetics are similar. Because of the brief duration of methohexital, two successive injections are made on each side rather than one, to lengthen the time available for testing both language and memory. Behavioral and EEG indices return to baseline more quickly and more completely with methohexital than with amobarbital, allowing several repetitions of the procedure without incremental drowsiness, and the total time taken for the procedure is less with methohexital than with amobarbital. CONCLUSIONS: The results of language and memory testing in the Wada test are equivalent for amobarbital and methohexital, except that methohexital has a briefer duration of action and is associated with less sedation.
