Six members of a family had a neurologic disease with autosomal dominant transmission and adolescent onset of progressive wasting of predominantly distal axial muscles and muscles innervated by cranial nerves V, VII, X, and XII, leading to severe morbidity in adulthood. Muscle biopsy of the propositus revealed "ragged-red" fibers, while electromyography and autopsy material were consisted with a neurogenic disease. The case seemed unique to any clinicogenetic nosology, because it was associated with a cardiac conduction defect, a mitochondrial abnormality in skeletal muscle, and a course, distribution, and degree of weakness that included features of both chronic spinal muscular atrophy and amyotrophic lateral sclerosis.

Thirteen patients suffering from motor neuron disease with dementia were studied to analyze the clinicopathological spectrum. The diagnosis of the disease was made on the basis of a clinical history of progressive dementia and motor neuron involvement. The mean age at onset of 11 sporadic cases was 54.9 years (range, 43 to 69 years), with a mean duration of disease of 25 months (range, 11 to 47 months). The initial symptoms were dementia in 7 cases, motor neuron involvement in 2 cases, and both dementia and motor neuron involvement in 2 cases. The clinical picture of motor neuron disturbance in sporadic cases represented bulbar-type of amyotrophic lateral sclerosis (ALS). Bulbar palsy was the initial symptom in 7 sporadic cases and all 11 patients developed bulbar palsy with advancing course of illness. Muscular wasting and fasciculation were more predominant in the upper limbs, shoulder girdle and anterior chest. Fasciculation was more extensively and frequently observed in those portions than that of classical ALS. In contrast, muscle strength in the lower limbs was well preserved so that all patients could walk even when respiratory failure developed. Hyperreflexia including jaw jerk was found in all cases and positive Babinski sign in 7 cases. Parkinsonism appeared in the initial stage in one sporadic case and in two familial cases. The type of dementia with uninhibited behavior and personality change closely mimicked that of Pick's disease. The degree of dementia was mild or moderate in 8 cases and severe in 3 cases. Language disorder was characterized by progressive reduction of speech output, leading finally to mutism in 5 cases. Perseveration was observed in 10 cases. Visuospatial disorder was absent even in the advanced stage. Mild memory disturbance was noted in the early stage in 10 cases. Pathological examination was performed in 7 cases including one familial case, revealing frontal atrophy in 3 cases, frontotemporal atrophy in 2 cases and temporal atrophy in 2 cases. On microscopic examination there were mild neuronal loss, gliosis, mild spongy state of the cortical superficial layers and fibrous gliosis in the frontotemporal white matter. The scattered senile plaques in one case did not justify a diagnosis of Alzheimer's type dementia. Neither circumscribed atrophy nor Pick body was found in any case. The nucleus basalis of Meynert showed no neuronal loss. The substantia nigra showed a mild to severe loss of nerve cells without Lewy bodies in all cases.(ABSTRACT TRUNCATED AT 400 WORDS)

The authors report the case of a 32-year-old woman who developed symptoms and signs possible manifestations of a familial motor neuron disease with left sided pyramidal signs and marked wasting and weakness in the ipsilateral upper girdle, progressively extended to the contralateral upper limb. The CT-scan showed only frontal cortical atrophy. MRI disclosed a restricted area of increased signal intensity in the centrum semiovale of the subcortical white matter of the right prefrontal cortex. This young woman did not disclose any risk factors for cerebrovascular diseases nor other disorders of the CNS; therefore the authors are of the opinion that the white matter changes observed on MRI are not occasional findings, but are related to the pathologic process occurring in consequence of her neurodegenerative disorder (possible ALS).

This is the first large scale case series of motor neurone disease (MND) in Thailand. Seventy-seven patients were identified between 1978 and 1984 at Siriraj Hospital Medical School, Bangkok, Thailand. Fifty-five patients were male (71.43%) and the mean age of the patients was 51.55 (SD 14.26) years with the range of 17 to 78 years. Clinical classification of MND was categorized as progressive bulbar palsy (PBP), 26 patients (33.77%); amyotrophic lateral sclerosis (ALS), 42 patients (54.54%); and progressive spinal atrophy (PSA), 9 patients (11.69%). The mean age of PBP, ALS and PSA were in the order of 57.61 (SD 12.09), 52.81 (SD 11.18), and 28.11 (SD 9.44) years. Progressive spinal atrophy group was younger than PBP and ALS groups significantly at the P-value less than 0.05 by analysis of variance and Duncan tests. Fifty-three patients (72.60%) were resident in Bangkok and the central part of Thailand. The main presenting symptoms were wasting of the small muscles of both hands, leg weakness, and speech and/or swallowing difficulties. These symptoms were found in 62 patients (81.58%). Nearly half of the patients (48.68%) came to our care within six months of onset, 22.8 per cent presented with asymmetry of motor wasting, while limb and trunk fasciculation was seen in 73.61 per cent. Dysarthria, dysphagia and tongue fasciculation were recorded as 51.32, 48.68, 60.53 per cent respectively. Exaggerated deep tendon reflexes were noted as 65.79 and 80.26 per cent over the upper and lower limbs, while Babinski sign was elicited in only 23.3 per cent of the patients.(ABSTRACT TRUNCATED AT 250 WORDS)

A spontaneous motor neuron disease or neuronopathy was identified in 10 horses from the northeastern United States. Signs of generalized weakness, muscle fasciculations, muscle atrophy and weight loss progressed over 1 to several months in young and old horses of various breeds. Pathologic studies revealed that degeneration and loss of motor neurons in the spinal cord and brain stem resulted in axonal degeneration in the ventral roots and peripheral and cranial nerves and denervation atrophy of skeletal muscle. Many spinal neurons were swollen, chromatolytic and contained neurofilamentous accumulations. Other cell bodies were shrunken and undergoing neuronophagia and some were lost and replaced by glia. This fatal equine motor neuron disease has not been reported previously and its cause has not been determined. The progressive weakness and wasting and the neuronal degenerative changes in these horses were similar to those described in people with sporadic amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease.

The distribution of muscle involvement, assessed clinically and electromyographically, was analyzed prospectively in 55 consecutive amyotrophic lateral sclerosis (ALS) patients and in 54 patients with other predominantly motor syndromes, some of whom were referred with suspected ALS. In ALS patients, distal limb muscles and thoracic paraspinal muscles were affected most frequently, more so than proximal limb and cranial muscles. The incidence of bulbar symptoms in ALS was greater in women than in men. These patterns suggest selective vulnerability of specific neuronal populations. The vulnerability of truncal muscles, illustrated by thoracic paraspinal wasting or head and shoulder drooping, was a helpful differential sign in diagnosing ALS. Thoracic paraspinal electromyography was especially valuable in distinguishing ALS from other disorders, such as combined cervical and lumbar spondylotic amyotrophy or polymyositis, which may masquerade as ALS. The finding of denervation atrophy on biopsy of thoracic paraspinal muscles was diagnostic in difficult cases. Because the thoracic paraspinal muscles are frequently affected in ALS and spared in spondylotic amyotrophy, their assessment provides a practical strategy in differentiating ALS from other motor syndromes.

The authors report 14 cases of late post-poliomyelitis muscular atrophies. The atrophy appears many years after the acute episode of anterior poliomyelitis. Several types of disorders were observed: extension of weakness and wasting; chronic spinal amyotrophy; amyotrophic lateral sclerosis without bulbar atrophy, coincidental muscular dystrophy. These cases have been interpreted in different ways. Further studies are necessary.

ALS and chronic spinal muscular atrophy are characterized by wasting of skeletal muscle, suggesting accelerated catabolism or reduced synthesis of muscle protein. We studied seven patients with ALS and three with chronic spinal muscular atrophy using 24-hour urinary 3-methylhistidine excretion as a measure of the rate of muscle catabolism and 24-hour urinary creatinine excretion as an index of significantly and similarly higher in both groups of patients than in controls (p less than 0.0005), implying a state of accelerated skeletal muscle protein catabolism in these diseases.

The authors report the case of a 16 year-old girl with the following features: clinically, a progressive bulbar paralysis, a weakness and wasting of muscles predominantly in the upper limbs; pathologically, a severe neuronal loss in the motor nuclei of the VIIth, IXth, XIIth cranial nerves and in the anterior horns of the cervical and thoracic spinal cord, a demyelinisation of the corticospinal tracts. A classification of progressive bulbar paralysies in infants and children is proposed. In the first group, the peripheral motoneuron is the only involved. Such cases are often called Fazio-Londe disease and can be related to those cases of infantile spinal amyotrophy either of the Werdnig-Hoffmann type or, most often, of the Wolfhardt-Kugelberg type. In the second group, the corticospinal tract is also involved. Some of these cases can be included in the spinocerebellar degenerations but others, such as the case reported here, are strongly reminiscent of the adult amyotrophic lateral sclerosis.

Familial occurrence of neuromuscular disease similar to sporadic amyotrophic lateral sclerosis has been reported from several countries. A Norwegian family with muscular wasting in men and women of three generations is described. The propositus and his father's sister were examined, as well as a second cousin of the propositus. The disease was characterized by late onset, predominantly upper limb peripheral pareses, and "pyramidal" signs in the lower extremities. Although peripheral neuromuscular affection in the lower limbs tended to be subclinical, chonchotome biopsies from the tibialis anterior muscle showed neurogenic atrophy in all three cases.
