Until such time as results of more rigorous studies are available, the morbidity rates for thyroid dysfunction cited here must suffice. The 1955 to 1956 outpatient "incidence" for England and Wales was 1.1 per 1,000 for thyrotoxicosis and 1.7 per 1,000 for myxedema (18). United States in-patient "incidence" for 1971 was 0.16 per 1,000 for thyrotoxicosis and 0.13 per 1,000 for myxedema (25). The 1935 to 1967 average annual incidence of Graves' disease for females in Olmsted County, Minnesota, was 30.5 per 100,000 (10). Well over 50% of hyperthyroid patients have clinical evidence of mild or moderate muscle weakness. Usually this weakness is proximal, and electro-myography and muscle biopsy confirm the existence of myopathic process (Table 11). Severe muscular weakness of acute onset is relatively rare and is encountered in approximately 1% of hyperthyroid patients (11,17,40). Ophthalmoplegia and psychosis are reported 4% and 2% of patients, respectively (17). Myasthenia gravis, although well publicized, is estimated to occur in less than 1% of patients (3,30). TPP is virtually nonexistent in the West; in the Orient it is reported in 2 to 8% of hyperthyroid patients and is 20 to 60 times more frequent in the hyperthyroid male than in the hyperthyroid female (Table 12). The neurologic symptomatology of myxedema is more extensive, and agreement among the various series is poor. The only unselected series addressing itself to neuromuscular manifestations of myxedema that is suitable for citation is that of Scarpalezos et al. (36). This comprehensive study was done without apparent patient selection, and it reported 2% of patients with definite carpal tunnel syndrome, 6% with myopathy, and 18% with polyneuropathy (Table 13). Reported percentages of hypothyroid patients found to have neurologic manifestations of cerebellar dysfunction are extremely diverse: ataxic gait was reported in 5 to 32% (6,7,12,27) of patients and dysdiadochokinesia in 6 to 52% (7,12,27). Psychosis is encountered in 2 to 5% (6,14,17,27,39) of myxedematous patients, memory loss in 23 to 55% (6,14,27), and coma in less than 1% (27).

In 1949, amphetamine sulfate was replaced by propylhexedrine in the nasal decongestant agent Benzedrex because of psychosis, sudden death, and widespread abuse. Propylhexedrine is not without risks, and reported cases of psychosis, myocardial infarction, pulmonary vascular disease and pulmonary hypertension, and sudden death are well documented in the medical literature. We are reporting 2 cases of definite brainstem dysfunction and 5 cases of transient diplopia secondary to IV abuse of Benzedrex. This widely abused drug is prepared by heating Benzedrex and hydrochloric acid, and the resulting crystals are dissolved in water for injection. This agent is called "stove-top speed". All 7 patients had transient diplopia, within seconds after injection. One patient had evidence of a right-internuclear ophthalmoplegia, and another had a depressed right gag reflex and paralysis of the right half of the tongue. The deficits in these two patients, persisted for many months. In young adults with history of drug abuse, the IV use of Benzedrex should be considered in the differential diagnosis of transient or permanent focal brainstem deficits.

The neurologic evaluation of an individual cardiac transplant recipient often does not lead to a succinct bedside diagnosis. There are few consistent clinical observations. The onset of seizures in the early postoperative period is associated with embolic cerebral infarction. Seizures occur most commonly, however, as a neurotoxic manifestation of cyclosporine. The onset of an acute delirium or psychosis in the first week after cardiac transplantation usually has multiple causative factors and is reversible. A postoperative brachial plexopathy or mononeuropathy can be identified with a neurologic examination, confirmed by appropriate electrophysiologic testing and is usually reversible. The onset of periorbital inflammation, ophthalmoplegia, and nasal turbinate or sinus invasion and necrosis is consistent with phycomycosis. Most patients, however, present with nonspecific findings of impaired mentation with or without focal neurologic signs. These patients require a fairly systematic search for potentially treatable neurologic complications (see Table 3). In a medically stable patient an aggressive diagnostic approach, at times including stereotaxic brain aspirate or biopsy, is indicated. In the severely ill patient with multiple organ failure, empirical therapy for the most probable treatable disorder is justified.

Niemann-Pick disease type C (NPC) is a neurometabolic genetic disorder that is distinguished from Niemann-Pick disease by its later onset, more insidious progression, variable visceromegaly, and abnormalities of intracellular cholesterol metabolism. We describe a patient who presented with an 8-year history of psychosis requiring chronic neuroleptic therapy for a presumed diagnosis of schizophrenia. He was subsequently diagnosed with NPC as the emerging features of dementia, ataxia, dysarthria, and vertical supranuclear ophthalmoplegia were recognized. The characteristic features of adult-onset NPC and the obstacles to early diagnosis are reviewed.

Progressive supranuclear palsy (PSP) is characterized by supranuclear ophthalmoplegia mainly affecting vertical gaze, nuchal dystonia in extension, pseudobulbar palsy, and mental changes. The literature on PSP has been neurologically oriented whereas the psychiatric aspects have been relatively neglected. A review of the literature shows that psychiatric disturbance in PSP is common but with no characteristic pattern. Cognitive impairment, nonspecific affective and behavioral disturbances are commonly found, whereas frank psychosis or bipolar disorder are rare. Misdiagnoses with psychiatric disorders are common and a heightened awareness of the condition is necessary for early diagnosis.

Thiamine deficiency is known to lead to certain neurological sequelae including Wernicke- Korsakoff encephalopathy. Signs attributable to this condition include ataxia, ophthalmoplegia, nystagmus, and mental confusion. Recognised predisposing conditions include alcoholism gastric carcinoma, pyloric obstruction, hyperemesis gravidarum, and prolonged intravenous feeding. We have recently encountered two cases of Wernicke's encephalopathy after vertical banded gastroplasty for morbid obesity . Other neurological sequelae are recognised after vertical banded gastroplasty, including Guillain-Barre syndrome, psychosis, and pseudoathetosis, but the causes are multifactorial.

A 65-year-old man was suffering from recurrent manic psychosis accompanied by weight loss. He also had a history of pleural effusion, aspecific migratory non-deforming seronegative polyarthritis, sensorineural hearing loss and semicircular canal paresis. Whipple's disease (WD) had been diagnosed at the age of 63 years. On admission to hospital) he had weight loss, diarrhoea in combination with an organic brain syndrome, hemiparesis and ophthalmoplegia, including internuclear ophthalmoplegia (INO). A clinical diagnosis of central nervous system (CNS) WD was made. MRI revealed a thalamus lesion that halved in size during sulfamethoxazole-trimethoprim treatment. The organic brain syndrome and ophthalmoplegia diminished also, as did the cerebrospinal fluid (CSF) IgG level. A review of CNS WD is presented and implications for treatment are discussed.

We report 10 children (7 male, 3 female), 3 homozygous for c.319C>T mutation and 7 heterozygous for c.319C>T on one allele and c.625G>A variant on the other in the short-chain acyl-CoA dehydrogenase (SCAD) gene (ACADS). All were of Ashkenazi Jewish origin in which group we found a c.319C>T heterozygote frequency of 1:15 suggesting the presence of a founder mutation or selective advantage. Phenotype was variable with onset from birth to early childhood. Features included hypotonia (8/10), developmental delay (8/10), myopathy (4/10) with multicore changes in two and lipid storage in one, facial weakness (3/10), lethargy (5/10), feeding difficulties (4/10) and congenital abnormalities (3/7). One female with multiminicore myopathy had progressive external ophthalmoplegia, ptosis and cardiomyopathy with pneumonia and respiratory failure. Two brothers presented with psychosis, pyramidal signs, and multifocal white matter abnormalities on MRI brain suggesting additional genetic factors. Two other infants also had white matter changes. Elevated butyrylcarnitine (4/8), ethylmalonic aciduria (9/9), methylsuccinic aciduria (6/7), decreased butyrate oxidation in lymphoblasts (2/4) and decreased SCAD activity in fibroblasts or muscle (3/3) were shown. Expression studies of c.319C>T in mouse liver mitochondria showed it to be inactivating. c.625G>A is a common variant in ACADS that may confer disease susceptibility. Five healthy parents were heterozygous for c.319C>T and c.625G>A, suggesting reduced penetrance or broad clinical spectrum. We conclude that the c.319C>T mutation can lead to wide clinical and biochemical phenotypic variability, suggesting a complex multifactorial/polygenic condition. This should be screened for in individuals with multicore myopathy, particularly among the Ashkenazim.

DNA POLG is the only mitochondrial DNA polymerase and is encoded by nuclear DNA. Depending on the location and inheritance, mutations in POLG1, the catalytic subunit, can cause symptoms including severe infantile epilepsy, metabolic strokes, chronic ataxia, neuropathy, and ophthalmoplegia. We reviewed medical records and conducted extensive interviews with the family of identical twin probands with a mutation in the linker region of DNA polymerase gamma 1 (POLG1) (G517V) and discuss postmortem findings from their grandmother. Both twins developed type I diabetes, adrenal insufficiency, hypothyroidism, and psychiatric problems in addition to neurological difficulties including bilateral basal ganglia infarcts, headaches, and seizures. The maternal grandmother, now deceased, had psychosis and balance problems, and postmortem findings include lacunar infarcts in the basal ganglia (caudate nucleus, putamen, and globus pallidus) and posterior spinal column degeneration. We discuss novel aspects of their presentation and implications for practice.
