Abstract
Autosomal dominant familial spastic paraplegia (AD-FSP) is a degenerative disorder of the central motor system characterised by progressive spasticity of the lower limbs. AD-FSP has been divided into pure and complicated forms. Pure AD-FSP is genetically heterogeneous; three loci have been mapped to chromosomes 14q (SPG3), 2p (SPG4), and 15q (SPG6), whereas no loci responsible for complicated forms have been identified to date. Here we report linkage to the SPG4 locus in a three generation family with AD-FSP complicated by dementia and epilepsy. Assuming that both forms of AD-FSP are caused by mutations involving the same FSP gene, analysis of recombination events in this family positions the SPG4 gene within a 0 cM interval flanked by loci D2S2255 and D2S2347.

Abstract
We report a family with an undiagnosed X linked condition. The grandmother, two of her three daughters, and one of her grand-daughters have a slowly progressive proximal weakness, brisk reflexes, poor bladder function, static reduced night vision, and IgG2 deficiency. The diagnosis of the three living symptomatic females was "hereditary spastic paraplegia plus". They have lost five male children who died in the neonatal period of severe hypotonia and were of low birth weight. Investigations have not led to a unifying diagnosis: myotonic dystrophy, NARP, and X linked hyper IgM were specifically eliminated. Using the hypothesis that the condition is X linked dominant, haplotype analysis of the family suggests that the disease locus is within Xq26-qter. This entity should be considered in the differential diagnosis of families presenting with severe neonatal hypotonia in males and females with symptoms suggestive of complex hereditary spastic paraplegia.

Abstract
We report three patients with slowly progressive spastic paraplegia and dementia; MRI on these patients revealed hypoplasia of the corpus callosum. The mode of inheritance was supposed to be autosomal recessive. Patient 1 (26-year-old man) is an elder brother of patient 2 (21-year-old man). Their parents are first cousins. Patient 3 (woman), a sporadic case, died of pneumonia at the age of 44. Their motor development after the birth was normal, but patient 3 was mildly mentally retarded. Gait disturbance due to spastic paraplegia developed at the age of nine (patient 2), fifteen (patient 1) and nineteen (patient 3), respectively. They also showed slowly progressive mental deterioration. Patient 1 has also suffered from mild amyotrophy and sensory disturbance in the distal part of the extremities since the age of 25. Patient 3 was bed-ridden at the middle of her thirty's because of generalized amyotrophy and sensory disturbance in addition to spastic quadriplegia and profound dementia. Their MRI reveal the thinning of the corpus callosum. We think the thinning must be hypoplasia of the corpus callosum, because the cerebrum showed normal appearance on MRI in patient 1 and patient 2. These clinical findings and imaging studies are essentially similar to those of the cases reported by Iwabuchi et al (1991). We propose autosomal recessive HSP associated hypoplasia of the corpus callosum as a new type of HSP.

Abstract
A large kinship is reported with dominantly inherited spastic paraplegia starting in the first decade of life; its clinical evolution was indistinguishable from that of "pure" hereditary spastic paraplegia (HSP). However, all patients studied had electrophysiological evidence of a predominantly sensory polyneuropathy, which was confirmed on nerve biopsy in three. The histological findings indicated virtually complete loss of large diameter fibres with relative preservation of small myelinated and non-myelinated fibres. The neuropathy was largely asymptomatic and there were no trophic ulcers. This family represents a distinct entity which differs from other reported cases of HSP with neuropathy by virtue of the clinical predominance of the pyramidal syndrome, the greater impairment of large fibre sensory modalities than of pain or temperature modalities, and the consequent absence of mutilation.

Abstract
Epilepsy rarely occurs in patients with hereditary spastic paraplegia (HSP), and is not included in the description of the 'complicated' form of HSP by Harding. We report 3 patients with HSP in a family of two generations. Two of them also had epilepsy, mental retardation and hearing impairment. The disorder was inherited as an autosomal dominant trait.

Abstract
Patients with hereditary spastic paraplegia (HSP), a degenerative central nervous system disorder characterized by progressive lower extremity spasticity, frequently experience symptoms of voiding dysfunction. Urodynamic evaluation of patients with HSP has not been reported, and the etiology of voiding dysfunction remains unexplained. We present our evaluation of three men (ages 42-62 years) with this rare syndrome. Urgency of urination was a uniform and dominant complaint, and two patients regularly experienced urge incontinence. Other symptoms included frequency (n = 3), nocturia (n = 3), and diminished force of stream (n = 1). Postvoid residual volumes were less than 25 ml in all patients. On urodynamic evaluation the two patients with urge incontinence displayed cystometric evidence of involuntary detrusor contractions. Pelvic floor EMG recordings suggested detrusor-sphincter dyssynergia (DSD). In addition, one patient exhibited markedly diminished bladder compliance (1.0 ml/cm H2O) and capacity (50 ml). All patients reported marked symptomatic improvement when treated with continuous intrathecal baclofen. Evaluation during baclofen treatment revealed increases in bladder compliance and capacity, with apparent resolution of DSD in one patient. Voiding symptoms in these patients most likely arise from a neurogenic etiology; however, a contributory role for chronic outlet obstruction from striated muscle spasticity may also exist.

Abstract
We describe a 37 year old man with a history of a gait disorder which had been worsening over a period of three years. Clinical examination showed the typical signs of a spastic tetraparesis with increased tone of all the extremities. Sensation, autonomic and cerebellar functions were not disturbed. Multiple exostoses had been present since early childhood, but none had been found in the spine or the cranium to cause the tetraspastic disorder. MRI scan was normal. Pedigree analysis of four generations showed that other family members were affected by both disorders. Chromosomal analysis was normal. We consider this to be a previously unknown hereditary syndrome transmitted as an autosomal dominant and manifesting a combination of spastic tetraparesis and multiple exostoses.

Abstract
Baclofen, a derivate of gamma-amino butyric acid (GABA), is known to be a useful drug in spasticity treatment. To achieve a good therapeutic response higher oral dosages have to be administered related with central side effects. Intrathecal application of Baclofen in microgram range dosages is proved to be effective in spinal spasticity. The efficiency of intrathecal Baclofen in patients suffering from supraspinal spasticity is discussed controversially. We report on 9 patients with long-term intrathecal Baclofen treatment, all of them responding well presenting a marked reduced muscle tone. In most cases an improvement of motor performance and in two cases improved bladder function was observed. The therapeutical dosages administered to patients with supraspinal spasticity exceed those administered to patients with spinal spasticity by approximately 100% without provoking central side effects. Despite the risks connected with this method it has to be considered as treatment of choice in cases of severe supraspinal spasticity.

Abstract
We describe 4 siblings with spastic paraparesis and peroneal amyotrophy who were prone to severe pain and painful dysesthesias, tetraparesis and pyramidal signs during pyrexial episodes of variable etiology. These symptoms cleared almost completely in 10-20 days. Nerve conduction velocity was reduced more markedly during the spells of fever. Muscle biopsy specimen was normal. Some transient functional disturbance of membrane equilibrium of the nervous pathways of both central and peripheral nervous systems was probably responsible for the attacks during pyrexial episodes.

Abstract
An autopsied case of complicated form of spastic paraplegia with many unusual clinical and pathological features is reported. Present case: a 31-year-old male. His parents are first cousins. Pregnancy and delivery had been unremarkable. Though he was mentally retarded, his physical development was normal. He was considered normal until age 10. He suffered from progressive disturbance in gait at the age of 11. He could not walk without assistance at the age of 22. Neurological examination revealed the following findings. He was obese and mentally deteriorated. Spastic paraplegia with increased tendon reflexes and pathological reflexes was prominent. Though slight sensory disturbance was present in the lower extremities, neither involuntary movement nor cerebellar ataxia was observed. In the age of late 20's, dementia, general muscular atrophy, and Parkinsonism developed. At the age of 30, he could not move by himself. He was apathic and indifferent, and showed forced laughing. Muscle tonus was flaccid because of general muscular atrophy and peripheral neuropathy. He died of acute gastric enlargement. Neuropathological findings were characterized by mal-development of the central nervous system (CNS) and the multisystem degeneration. There existed cerebral white matter hypoplasia with hypogenesis of the corpus callosum and ectopia of neurons of the cerebral and cerebellar cortex. Hypoplasia of melanin pigment was also observed in the remaining neurons of the substantia nigra and the locus ceruleus. Many neurons in the CNS included lipofuscin granules of variable shapes. Some of them showed clusters of several block-like inclusions which were green with luxol fast blue and cresyl violet stain.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
We report a family with May-Hegglin anomaly associated with familial spastic paraplegia. The propositus was a 39 year old male. His peripheral blood showed a Döhle-like inclusion bodies in WBC, giant platelets, and thrombocytopenia. He had been suffering from progressive gait disturbance of spastic paraplegia since 20 years old. He was in a state of chronic renal failure and showed sensory hearing impairment. His two children showed similar hematological abnormalities and spastic gait. As far as we know, this is the first case of May-Hegglin anomaly associated with familial spastic paraplegia in the literature.

Abstract
A woman aged fifty-three developed paraparesis at the age of 4, which progressed slowly and required crutches by the age of 30. At the age of 51, muscle stiffness involved bilateral hands and arms gradually. At the age of 53, she suffered from painful spasms in right deltoid muscle. Her two brothers had spastic paraplegia without other neurological deficits. Her paternal grandfather and maternal grandmother were cousins. Slight dementia was noted (WAIS: IQ, 79). Her posture was stiff and muscles of upper limbs were in a persistent contraction; Subcutaneous tissue was thin, and muscles were well-defined and firm. There was moderate muscle weakness of legs and hands. Continuous fasciculations and myokymias were recognized in muscles of the arms and the limb girdles. Muscle tone was considerably increased especially in the bilateral arms. The deep tendon reflexes were exaggerated with extensor plantar responses. Profuse sweating affected palms, soles and backs. No sensory disturbance was appreciated. There was no myotonic responses to percussion of muscles. Following laboratory data were normal; thyroid functions, CSF studies, anti HTLV-I antibody and long chain fatty acid in red blood cells, myelography and brain CT except for increased basal metabolic rate (53%). Electromyographic study in the arms and hands revealed spontaneous motor unit activities including doublets at rest and increased proportion of polyphasic potentials and high amplitude potentials in voluntary contraction. Biopsy of right quadriceps femoris muscle showed hypertrophy of type I fibers and angulated atrophy of type II fibers. Continuous muscle activities in upper limbs did not change at sleep or with intravenous administration of 7 mg diazepam.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Familial spastic paraparesis with amyotrophy of the hands was reported, and its significance in the literature was reviewed. Case 1: An 18 year-old boy, who had been suffering from spastic gait since 12 years old, noticed his hand muscle wasting distributed bilateral first interosseous muscle, thenar and hypothenar muscle at age 17. Case 2: A 20 year-old man, elder brother of case 1, who also walked in spastic manner from his childhood, developed bilateral hand muscle atrophy similar to case 1 at age 19. Clinical features of these two cases could be summarized as familial spastic paraparesis with amyotrophy characterized by hand muscle atrophy, spasticity of lower extremities with hyperreflexia and bilateral positive pathological reflexes and spastic gait. Their younger sister was also examined, who showed only minimal spastic paraparesis. The electrophysiological examination including EMG and SEP suggested the pathological process could involve not only lateral column, but also posterior column and anterior horn. Slight but generalized spinal cord atrophy was demonstrated on metrizamide CT myelography. The muscle biopsy performed from left gastrocnemius in case 2, confirmed neurogenic changes. Although the association of retinal degeneration, cataracta, mental retardation, pes cavus or even generalized amyotrophy has been reported in familial spastic paraparesis, only limited cases are available, dealing with the amyotrophy of limbs. As far the cases with amyotrophy localized to the hands are concerned, it is absolutely rare and only the cases reported by Silver could be regarded as similar or same clinical entities to our cases.
