25. Dystonic-Parkinsonian syndrome after cyanide poisoning: clinical and MRI findings.
Progressive Parkinsonism, dystonia and apraxia of eye opening were seen after cyanide poisoning. CT scan and MRI showed lesions in the basal ganglia, cerebellum and cerebral cortex consistent with reported pathological findings.

26. Arterial spasm and slowing of the cerebral circulation in the ischaemia of head injury
Carotid angiograms of 33 patients who had died during 1968 and 1969 from blunt head injury were reviewed and assessed for evidence of arterial spasm and slowing of the cerebral circulation. Spasm was found in 57·5%, a prolonged circulation time in 57·5%, and a combination of both features in 42·4% of cases. In the same group of patients there was also a h

27. Extrapyramidal dysfunction with cerebral arteriovenous malformations 1
Arteriovenous malformations have only rarely been implicated as a cause of basal ganglia dysfunction. In four instances where such a lesion was uncovered, abnormal involuntary movements were present. In two, tremor involving the contralateral limbs occurred, while in others the head and neck were involved in dystonic movements and posture. The clinical and a

28. Apraxia in deep cerebral lesions.
In a series of 50 patients with cerebrovascular lesions (demonstrated with CT scan), seven patients had lesions located in the basal ganglia and/or thalamus. All these seven patients were apractic. Ideomotor apraxia was present in all patients; five also had constructional apraxia, and one had bucco-facial apraxia. None of the patients had utilisation apraxi

29. Neuropeptide proctolin (H-Arg-Tyr-Leu-Pro-Thr-OH): immunological detection and neuronal localization in insect central nervous system.
Proctolin (H-Arg-Tyr-Leu-Pro-Thr-OH) is a pentapeptide first extracted from cockroaches. It is known to have many neurohormonal effects and has been associated with specific, identified cockroach neurons. We have produced proctolin antisera and report here on their application in detecting proctolin-like immunoreactivity (PLI) in the cockroach central nervou

30. Specificity of changes in cerebral blood flow in patients with frontal lobe dementia.
Eight patients with a clinical diagnosis of probable Alzheimer's disease, eight patients with the clinical diagnosis of frontal lobe dementia, and eight controls were examined with single photon emission tomography (SPECT) using 99Tc-HMPAO. Patients with Alzheimer's disease and those with frontal lobe dementia met DSM-III-R criteria for mild dementia and wer

31. Calcitonin gene-related peptide: functional role in cerebrovascular regulation.
Distribution studies disclosed that all major cerebral arteries and cortical arterioles of the cat were invested with fine varicose nerve fibers that contained calcitonin gene-related peptide (CGRP)-like immunoreactivity; the trigeminal ganglia likewise contained CGRP immunoreactivity. Sequential immunostaining with antibodies to CGRP and to substance P (SP)

32. Rapid correction by 1-α-hydroxycholecalciferol of hemichorea in surgical hypoparathyroidism
A 45-year-old woman with long standing surgical hypoparathyroidism presented with right hemichorea of three months' duration. She had profound hypocalcaemia and hyperphosphataemia and extensive cerebral, cerebellar and basal ganglia calcification. Correction of the chemical abnormalities with 1α-hydroxycholecalciferol, calcium supplements and aluminium hydr

33. HMPAO SPECT in Parkinson's disease before and after levodopa: correlation with dopaminergic responsiveness.
Regional cerebral perfusion was evaluated by SPECT with technetium 99m hexamethylpropyleneamine oxime (99mTc HMPAO) as a tracer in 21 patients presenting with Parkinson's disease and in 11 normal controls. In the parkinsonian patients, scans were performed both off treatment, and after levodopa, and clinical dopaminergic responsiveness was evaluated. Uptake

34. The metabolic effects of limbic leucotomy in Gilles de la Tourette syndrome.
Regional cerebral oxygen metabolism was measured before and after limbic leucotomy in a patient with Gilles de la Tourette syndrome, obsessive compulsive disorder, and obsessional slowness. The preoperative scan showed hypermetabolism in the caudate nuclei, which normalised after operation. It is proposed that the beneficial effects of this operation on both

35. New phenotype of the cerebral autosomal dominant arteriopathy mapped to chromosome 19: migraine as the prominent clinical feature.
A survey was carried out on a large family presenting the symptoms of familial arteriopathy (CADASIL) recently mapped to chromosome 19. This is characterised clinically by recurrent subcortical infarcts developing into pseudobulbar palsy and subcortical dementia, and radiologically by early MRI abnormalities. To characterise this familial condition, 43 membe

36. Prospective evaluation of cerebral angiography and computed tomography in cerebral haematoma.
One hundred and two consecutive patients with cerebral haematoma were prospectively allocated to one of two groups according to their CT on admission. Group 1 patients were thought to have a high probability of an underlying structural lesion and underwent cerebral angiography acutely. If normal, this was repeated at three months. Group 2 patients were thoug
