A case history is reported of a 44-year-old man with a 6-year history of psychomotor seizures. For the past year he had described persistent olfactory hallucinations of an unpleasant nature which he referred to himself. In many respects these symptoms conform to the pattern observed in the olfactory reference syndrome, a recently described but apparently quite discrete psychiatric disorder; there were, however, certain atypical features. At a later stage unilateral anosmia was noted. Radiological examination then demonstrated an arterio-venous malformation in the right frontal lobe. The relationship between the malformation and the psychomotor seizures, and the implications that each has for the development of an olfactory reference syndrome are fully discussed.

A case of giant aneurysm arising from the anterior communicating artery, 24 X 28 X 30 mm in diameter was found in a 30 year old man. About ten years ago he became blind and recently developed right anosmia and diencephalic seizures. No subarachnoid hemorrhage, however, was found. Radiograms and tomograms of the cranium showed a ring-like calcification, but by angiography it couldn't be recognized as a giant aneurysm. The right frontal craniotomy and partial resection, therefore, was performed. A histological study of the resected material revealed that it was a spontaneously thrombosed giant aneurysm. The inner layer of its wall had neither endothelium nor elastic lamina, but had deposits of calcium salt. The outer layer was composed of collagen fibers without cell infiltration. The aneurysm was thrombosed except for its neck but its organization occurred incompletely. We want to emphasize the importance of a correct preoperative diagnosis, as an erroneous operative procedure can result in disaster. Volume, viscosity and tension of flowing blood into the aneurysm as well as the size of its neck and dome regulate dynamic properties. These properties may determine the enlargement rate or growth of the aneurysm. The dynamic characteristics and features of the inner surface of the aneurysmal wall may regulate the formation of thrombosis in the aneurysm. The intraluminal thrombosis and strength of aneurysmal wall, for example, calcium deposits, may prohibit aneurysm from its rupture.

The results of a retrospective survey of 48 patients submitted to neurosurgery for medically intractable epilepsy are presented. Twenty-eight patients were treated with selective amygdalohippocampectomy, one with temporal lobe resection, 12 with anterior callosotomy and seven with a total callosotomy. Of the amygdalohippocampectomized patients and the one with temporal lobe resection (n = 29), 52% were seizure free, 17% experienced rare seizures, 7% had a worthwhile improvement while 24% observed no worthwhile improvement (follow-up time 6 to 36 months). Of the callosotomized patients, 11% were free from generalized seizures, 69% had a significant seizure reduction and 18% experienced no worthwhile improvement. The observed neurological complications were: one patient had hemianopia, one had superior quadrant anopia, four developed unilateral anosmia and one complete anosmia. The callosotomized patients, with two exceptions, were all mentally and physically handicapped. In the callosotomy group, two patients died, one from a intracerebral hematoma three months after the operation and another patient seven months postoperatively from unknown causes.

We describe a familial disorder consisting of sleep apnea, anosmia, colorblindness, partial complex seizures, and cognitive dysfunction. The phenotypic expression of the syndrome suggests an autosomal dominant inheritance with incomplete penetrance.

In a retrospective study of 4,294 consecutive postmortem cases, there were 15 with histologically proved sarcoidosis, including 4 with CNS involvement. Whereas in previously reported autopsy series the prevalence of neurosarcoidosis was 15%, it is 27% in this review. Five cases with incidental, clinically inapparent sarcoidosis died at a mean age of 54.6 years; those six with systemic sarcoidosis, not involving the CNS, died at a mean age of 47.0 years; while those four with a variety of neurologic manifestations in addition to systemic sarcoidosis died at a mean age of 38.2 years. Thus, it appears that at one end of the spectrum of morbidity, sarcoidosis may cause no or only trivial symptoms and permit prolonged survival. At the other extreme, sarcoidosis may affect a younger population more severely. CNS involvement occurs relatively early in the course and its rather rapidly progressive, accounting for the poor prognosis, despite appropriate medical and neurosurgical management. In its turn, neurosarcoidosis may present with a variety of signs and symptoms, depending on the site of involvement along the craniospinal axis. This feature is illustrated by the manifestations of compression myelopathy, hydrocephalus with dementia, hydrocephalus with seizures and ataxia, and anosmia, blindness, seizures, and diabetes insipidus. In addition, one patient developed a Nocardia brain abscess as a complication of the altered immune system in sarcoidosis.

About two million Americans suffer from anosmia. Most result from nasal obstruction, head injuries, and viral infections. Brain disorders like epileptic seizures, tumours, and dementia can distort can distort the sense of smell. Anosmia adversely affects patient well-being. Patients cannot detect spoiled food, gas leakage, or dangerous smoke. They are unable to distinguish flavour and smell the springtime or the ocean. Many products as soaps, cat litter, toilet paper, etc. are perfumed because consumers will more readily buy a product that smells nice than one that has no smell at all. Historically, the importance of odors was very different. The ancient Romans loved exotic aromas during their banquets and orgies. In the Middle Ages the church did not like fragrances. The French revolution of 1789 brought a revolution of deodorization to Europe. Today, fragrance companies' increasing sales are an indication of the power of odor.

Wolfram's syndrome, also known as DIDMOAD syndrome, includes juvenile diabetes mellitus and optic atrophy variously associated with diabetes insipidus and deafness. We describe the neurological findings in 5 patients with Wolfram's syndrome. All patients had a neurological examination and were subjected electrophysiological and brain imaging including CT scan and, in one patient, MRI. There were two pairs of brothers and a sporadic case with paternal consanguinity suggesting recessive inheritance. Neurological abnormalities were found in four patients including dysarthria, seizures, anosmia, nystagmus, ataxia and changes in the electroencephalograms, electroretinograms and evoked potentials. In contrast with previous reports, four patients had abnormal brain CT scan with prominent atrophy of the brainstem. In the patient studied with NMR, severe brainstem and cerebellar atrophy was found. These neuroradiological findings are reminiscent of those described in olivopontocerebellar atrophy and are in agreement with previous pathological studies. We conclude that Wolfram's syndrome includes phenotypical manifestations of olivopontocerebellar atrophy. This reinforces the opinion that olivopontocerebellar atrophy is a nonspecific syndrome of varied causes.

Two patients with superficial siderosis of the central nervous system are reported. Both developed progressive deafness over many years; one with associated anosmia and partial seizures; the other with progressive ataxia and diplopia. The cerebrospinal fluid was xanthochromic in one and the protein was raised in both. Magnetic resonance imaging revealed a hypodense rim around the eighth cranial nerve, cerebellum, brain stem and spinal cord. Despite extensive investigations the cause of the superficial siderosis in both patients remains undetermined.

Mild traumatic brain injury (TBI) encompasses the postconcussion syndrome characterized by symptoms that include a variety of physical symptoms as well as cognitive and behavioral impairments. The focus of this discussion is on the medical management of posttraumatic headaches, posttraumatic seizures, dizziness, auditory impairments, anosmia, tremor, paraspinal pain, and visual symptoms. Adjustment disorders with disturbances of affect and emotion lability also may accompany mild TBI. All of these conditions may be approached with medications or a variety of therapy techniques or both. The approach to concussion in sports-related injuries is also reviewed.

Subfrontal schwannomas are rare intracranial tumors. Most of them are associated with hyposmia/anosmia. The source of origin of these tumors is still incompletely understood. We report a 23-year-old male who presented with recurrent focal motor seizures, but had no hyposmia. The tumor was completely removed by a subfrontal approach. Relevant literature has been reviewed.
