Methylphenidate to Improve Balance and Walking in MS

2014-08-27 04:00:43 | BioPortfolio

Summary

Methylphenidate is an amphetamine-like psychomotor stimulant drug currently approved for the treatment of attention-deficit hyperactivity disorder (ADHD), postural orthostasis tachycardia syndrome and narcolepsy. It is also often prescribed off label to people with MS to improve fatigue. It is proposed that methylphenidate may also improve imbalance and walking deficits in MS by improving concentration and central integration, one of the primary mechanisms thought to underlie imbalance and walking deficits in MS.

Description

The proposed pilot study will examine the effects of methylphenidate on imbalance and walking in 24 subjects with MS and imbalance. The subjects will be randomly assigned to receive either an escalating does of methylphenidate, 20mg, 40mg or 60mg, divided into two doses each day, or matched placebo for 2 weeks at each dose. If a subject does not tolerate dose escalation they will be instructed to discontinue use of the drug. The maximum safely tolerated dose for each subject will be noted. Changes from baseline in subject's walking speed, balance, vestibular function, cognitive function, and fatigue will be assessed at each dose.

Medical and Biotech [MESH] Definitions

A form of multiple sclerosis characterized by a progressive deterioration in neurologic function which is in contrast to the more typical relapsing remitting form. If the clinical course is free of distinct remissions, it is referred to as primary progressive multiple sclerosis. When the progressive decline is punctuated by acute exacerbations, it is referred to as progressive relapsing multiple sclerosis. The term secondary progressive multiple sclerosis is used when relapsing remitting multiple sclerosis evolves into the chronic progressive form. (From Ann Neurol 1994;36 Suppl:S73-S79; Adams et al., Principles of Neurology, 6th ed, pp903-914)

A non-glycosylated form of interferon beta-1 that has a serine at position 17. It is used in the treatment of both RELAPSING-REMITTING MULTIPLE SCLEROSIS and CHRONIC PROGRESSIVE MULTIPLE SCLEROSIS.

An autoimmune disorder mainly affecting young adults and characterized by destruction of myelin in the central nervous system. Pathologic findings include multiple sharply demarcated areas of demyelination throughout the white matter of the central nervous system. Clinical manifestations include visual loss, extra-ocular movement disorders, paresthesias, loss of sensation, weakness, dysarthria, spasticity, ataxia, and bladder dysfunction. The usual pattern is one of recurrent attacks followed by partial recovery (see MULTIPLE SCLEROSIS, RELAPSING-REMITTING), but acute fulminating and chronic progressive forms (see MULTIPLE SCLEROSIS, CHRONIC PROGRESSIVE) also occur. (Adams et al., Principles of Neurology, 6th ed, p903)

The most common clinical variant of MULTIPLE SCLEROSIS, characterized by recurrent acute exacerbations of neurologic dysfunction followed by partial or complete recovery. Common clinical manifestations include loss of visual (see OPTIC NEURITIS), motor, sensory, or bladder function. Acute episodes of demyelination may occur at any site in the central nervous system, and commonly involve the optic nerves, spinal cord, brain stem, and cerebellum. (Adams et al., Principles of Neurology, 6th ed, pp903-914)

Multiple protein bands serving as markers of specific ANTIBODIES and detected by ELECTROPHORESIS of CEREBROSPINAL FLUID or serum. The bands are most often seen during inflammatory or immune processes and are found in most patients with MULTIPLE SCLEROSIS.
