Anterior horn cell dysfunction in Alzheimer's disease.
Electrophysiological studies were undertaken on 29 patients with Alzheimer's Disease. A reduction in the number of functioning motor units was found in the extensor digitorum brevis muscle. The electrophysiological parameters of the motor unit potentials were increased compared to control values. Four of seven muscle biopsies showed abnormalities ranging from mild to severe. The results suggest...
متن کاملSuperficial siderosis.
Case 1 An elderly patient presented with insidious onset of sensorineural hearing loss. The past history was unremarkable except for insidious onset of weakness of left lower limb. Physical examination revealed left hemiparesis with upgoing left plantar. Magnetic resonance imaging (MRI) of brain revealed a large flow void in the interpeduncular cistern suggestive of aneurysm arising from the to...
متن کاملSuperficial siderosis of the CNS associated with multiple cavernous malformations.
Superficial siderosis of the CNS due to chronic, recurrent subarachnoid hemorrhage is an uncommon and potentially debilitating disorder. The classic clinical manifestation is progressive bilateral sensorineural hearing loss (SNHL), although ataxia and pyramidal signs also are observed frequently. Cavernous malformations rarely present with subarachnoid hemorrhage. We describe an unusual case of...
متن کاملSuperficial cortical siderosis.
Cerebrovascular deposition of amyloid (cerebral amyloid angiopathy CAA) is most commonly recognized as a cause of spontaneous lobar intracerebral hemorrhage. On the basis of the noninvasive new MR imaging we would propose superficial cortical hemosiderosis and subarachnoid hemosiderosis as potentially useful new criteria to facilitate the diagnosis of CAA.
متن کاملCochlear implant patients with superficial siderosis.
BACKGROUND Considered a rare disorder, superficial siderosis of the central nervous system (SSCN) has become more frequently diagnosed in recent years. As it is characterized by progressive sensorineural hearing loss, patients' needs may surpass the capability of hearing aid technology. Despite the retrocochlear nature of the disorder, patients have undergone cochlear implantation (CI) with var...
