The clinical features of 12 patients with spasmodic dysphonia are described. In 11 patients, the voice was strained, harsh, tight, and tremulous, and was low in volume and pitch. Speech, which was sometimes barely intelligible, was interrupted by irregular stoppages and catches of the voice; it required considerable effort, and was accompanied by facial grimacing. The dysphonia was part of a more widespread neurological disorder (idiopathic torsion dystonia) in one case, while it coexisted with blepharospasm in another, and with postural tremor in two. There was a buccolingual hyskinesia in another of these 11 patients, but this may have been related to her previous drug regime. In the twelfth patient, who had a familial tremor, the voice was characterised by marked breathiness, with intermittent aphonia. The disorder is probably due to a focal dystonia of the laryngeal musculature, and this would be consistent with the type of neurological disorders that were associated with it in our cases. Symptomatic benefit follows the therapeutic division of one of the recurrent laryngeal nerves, in selected cases.

We studied a 68-year-old man who died after 13 years of progressive dementia, rigidity, bradykinesia, mild tremor, stooped posture, slow and shuffling gait, dystonia, blepharospasm, apraxia of eyelid opening, anarthria, aphonia, and incontinence. At autopsy, he had generalized brain atrophy with large deposits of iron pigment in the globus pallidus, caudate, and substantia nigra. Axonal spheroids were found in the globus pallidus, substantia nigra, medulla, and spinal cord. The neurochemical analysis of the brain revealed marked loss of dopamine in the nigral-striatal areas, with relative preservation of dopamine in the limbic areas. This is the oldest case of familial Hallervorden-Spatz disease reported and the first with neurochemical analysis of the brain.

The clinical and pathological features of a newly recognized, inherited neurodegenerative disorder in horned Hereford calves are described. The disorder is expressed in newborns by tremulous shaking of the head, body and tail, difficulty in rising, a wobbly spastic gait, and aphonia. Transient improvement is followed by deterioration and progressive spastic paraplegia. Generalized tremors can be induced easily by a variety of stimuli, and spinal reflexes may be exaggerated or depressed. The major pathological finding is an excessive accumulation of neurofilaments within neurons of the central, peripheral, and autonomic nervous systems. The involvement of multiple systems of neurons and the similarity with some forms of human motor neuron disease and spinocerebellar degeneration suggest that this unique bovine disease may serve as a suitable animal model for these human neurodegenerative disorders.
