Alcohol withdrawal syndromes in humans lie on a continuum of increasing severity, from the acute hangover to delirium tremens. Early mild reactions consist primarily of hyperexcitability phenomena such as tremor, insomnia, hyperreflexia and hyperventilation. In more severe degree, the same process gives rise to hallucinations and seizures. These early reactions are mimicked closely by alcohol withdrawal signs in experimental animals. Late reactions in humans are characterized by marked sympathetic nervous system overactivity, profound disorientation and hallucinations. Analogous reactions have not yet been observed clearly in other species. The problem may be one of finding appropriate techniques for detecting such changes, rather than a true species difference in their occurrence.

We have reviewed 14 cases of water intoxication in psychiatric patients. In these cases the possibility of the syndrome of inappropriate antidiuretic hormone secretion (SIADH) was suspected or diagnosed. The SIADH should be suspected in psychotic patients who drink water excessively, develop seizures, disorientation and deterioration of mental status.

A case is reported of a former woman astronaut candidate who withstood the rigors of the preliminary physical examinations for this position. Some years later, she sustained a subarachnoid hemorrhage from an arteriovenous malformation in the right parieto-occipital area, which was successfully excised. Postoperatively, she had a marked visual deficit, from which she completely recovered within 3 months. The development of psychomotor seizures 5 months later was due to probable scarring in the right parieto-occipital region of the cerebral cortex, the interpretive area for orientation of body image in space, which had been supplied by the clipped right anterior and posterior cerebral arteries feeding the arteriovenous anomaly. These seizures have been well controlled on anticonvulsants. A lesion in the temporoparieto-occipital region due to a hemorrhage from a ruptured arteriovenous anomaly, resulting in the disabling symptoms of disorientation or loss of body image due to impairment of the interpretive cortex, could be devastating to the pilot and a mission. This case raises the question of an automatic use of the CT brain scan in screening potential space candidates, and even the consideration of a percutaneous femoral four-vessel arteriogram in all, or possibly selected, candidates. Most neurosurgeons and neuroradiologists probably would consider the risks of the latter procedure too great to justify its use for fear of permanent complications to the space candidate.

Nine patients with intracerebral metastasis from lung carcinoma were treated with intracarotid and intravertebral artery infusion of 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU). Four of these patients considered definite responders showed unequivocal clinical improvement and definite decreases in the size of tumors evaluated by neurologic examination, computerized tomographic (CT) scan and radionuclide brain scan (RBS). One patient's clinical condition stabilized with doubtful improvement of diagnostic tests (probable responder). The remaining four patients had further unfavorable progression of the clinical and scan findings and were clearly nonresponders. Complications were transient and included: local pain in the eye, orbit, and occipital-nuchal area during infusion in 7 patients, focal seizure in 3 patients, mild confusion with disorientation in 2 patients, and nausea in 2 patients. Our findings suggest that intra-arterial BCNU therapy may be effective and may be used as an adjuvant to surgery and/or radiotherapy for the treatment of metastatic brain tumor from lung carcinoma.

A 36-year-old man with prolonged confusion developed after psychomotor status was reported. He had no past history of epileptic seizures or psychotic disorders. The status continued for 20 hours, and twilight state and a slight fever lasted for about 10 days. Thereafter gross impairment of memory and disorientation became remarkable, and, in addition, strong psychic and autonomic disturbances developed, such as visual and auditory hallucinations, excessive excitement, disturbance of sleep, polyphagia, polydypsia, polyuria and hyperhidrosis. The CT scan, carotide angiography, CSF examination, and complement fixation tests for viruses were all within normal limits. The EEGs showed a slowing of the background activity, 0.6--0.8 Hz periodic high voltage wave discharges and random spikes in each temporal area. The clinical symptoms and EEG findings gradually improved without remarkable damage.

Post-shunt subdural hematoma was found in two patients with hydrocephalus due to subarachnoid hemorrhage. The first case was a 46-year-old man with two episodes of subarachnoid hemorrhage from anterior communicating aneurysm. Two weeks after neck-clipping for the aneurysm, a ventriculo-peritoneal shunt with Pudenz's system was performed since hydrocephalus with moderately increased pressure had been found. He did well for one month, then soon after mild head injury, disorientation and right hemiparesis developed. Cerebral angiogram revealed avascular space in the left parietotemporal region. After the ligation of the shunt tube, subdural hematoma was removed. The symptoms improved in two weeks. The second case was a 62-year-old man with an aneurysm at the trifurcation of the right middle cerebral artery. One month after successful clipping of the aneurysm, he received a ventriculoperitoneal shunt with Pudenz's system for normal pressur hydrocephalus. One and a half years after the operations he hit his head against the ground during his convulsive seizure. Since then, disorientation, urinary incontinence and gait disturbance appeared. After cerebral angiogram, the subdural hematoma was removed and the shunt tube was ligated. He became free of these symptoms in two weeks. The cerebrospinal fluid shunt is recommended for hydrocephalus induced by subarachnoid hemorrhage, but careful follow-up is necessary since these patients might develop post-shunt subdural hematoma, especially after head trauma as shown in our cases.

Hypo- and hypertension, arrhythmias, bradycardia extending to cardiac arrest with circulatory failure, pneumothorax, allergic reactions with or without anaphylactic shock, production of methaemoglobin, vomiting, vertigo, disorientation, acoustic and visual disorders, tinnitus, slurred speech, muscle contractions, unconsciousness, and epileptic seizures are well-known complications associated with local anaesthetics. We have observed an additional central nervous system complication: a case of transient, total motor aphasia (Broca aphasia) in a 50-year-old patient after axillary blockade of the brachial plexus. Possible causes such as type and dosage of local anaesthetic or a transient ischaemic attack in the area of the prerolandic artery are discussed and related to the literature. Ultimately, however, it is still not apparent why this complication could appear although there was no overdosage intravascular injection, or abnormality of the pulse or blood pressure, and why its manifestation was limited to a motor aphasia.

A 50-year-old black man with steroid-dependent stage IV sarcoidosis and a prior seizure attributed to neurosarcoidosis had progressive disorientation, ataxia, cranial neuropathies, and increased dyspnea. Neuroradiologic evaluation showed a ring-enhancing lesion in the left basal ganglion causing a mass effect. Craniotomy yielded purulent material that grew a pure culture of Listeria monocytogenes. He responded well to antibiotic therapy.

A 46 year old woman had a relapsing-remitting course of hemiparesis, disorientation, paraparesis and seizures, followed by progressive dementia, spasticity and ataxia. Computed tomography at onset showed a parietotemporal hypodense area with diffuse mottled enhancement obliterating the lateral ventricle. Subsequent scans demonstrated symmetric periventricular non-enhancing hypodensities, progressive ventricular enlargement and atrophy. Adult metachromatic leukodystrophy was diagnosed on the basis of low leukocyte arylsulphatase A level and metachromatic material accumulation at neural nerve biopsy.

We report a case of gliomatosis cerebri in a 46-year-old woman with five-year history of seizures and psychiatric disturbance. There were also two episodes of lethargy, disorientation, and headache which cleared promptly with Mannitol. A 3rd episode terminated in her death. Remarkably, between the episodes of presumed increased intracranial pressure, the neurologic examination was normal except for the patient's denial of her illness. Postmortem examination revealed the entire right cerebral hemisphere to be enlarged and infiltrated by cells resembling astrocytes. The clinical signs, symptoms, and controversial histopathologic features of this rare entity are discussed.
