A Study of Treatment with Ethyl-eicosapen taenoate in Patients with Huntington's Disease (Ethyl EPA)

HUNTINGTON'S DISEASE CLINIC

Ethyl EPA is a drug trial for symptomatic individuals conducted in collaboration with Laxdale Ltd.

Overview

The purpose of this trial is to analyze the effect of ethyl-eicosapentaenoate (ethyl-EPA) on chorea, mood, and mental functioning. Ethyl-EPA may prevent degeneration of nerve cells by preventing stress and damage to their external and internal membranes.
