Official Title: Screening and Natural History: Primary Lateral Sclerosis and Related Disorders
Brief Summary:
Objective:
The objectives of this protocol are:
to develop and maintain a repository of clinically characterized patients with primary lateral sclerosis for future research protocols,
to characterize the natural history of neurodegenerative disorders with corticospinal neuron degeneration,
to investigate proposed etiologies, risk factors, and biomarkers for the development of these disorders and for disease progression
Study Population:
240 patients with adult-onset progressive spasticity with a diagnosis of primary lateral sclerosis or related upper motor neuron disorder
Design:
Patients who have been referred by physicians for primary lateral sclerosis will undergo a screening evaluation at the first visit. The screening visit will include review of outside medical records, neurological examination, and diagnostic testing to determine possible causes of spasticity. Patients fulfilling the clinical criteria for primary lateral sclerosis by history or examination will be followed to determine the natural history of this disorder. Measures of motor and cognitive function will be made at baseline and follow-up visits to follow clinical progression. Magnetic resonance imaging will be carried out to determine if imaging changes occur over time. Patients identified in this protocol who are eligible for other research protocols will be invited to participate in additional protocols.
Outcome Measures:
Clinical progression will be documen
