because of continuous changing of anatomy, function and metabolism of the human brain, age- related change is a major risk factor in most prevalent neurodegenerative diseases, including parkinsons and huntingtons disease. therefore, knowing patterns of age-related atrophy of brain tissue can identify causes and possible role of diseases in decreasing brain function with age. the aim of this stu...

huntingtons disease (hd) is an autosomal dominant inherited disease characterized by involuntary movements, behavioral and personality changes, dementia and cognitive decline. although the mean age of onset is about 40 years, it varies from 5 to 79 years. therefore, at-risk individuals are never sure to have escaped the disease. hd is a member of the growing family of neurodegenerative disorder...

Huntingtons disease (HD) is an autosomal dominant neurodegenerative disease. Accordingly, 3-nitropropionic acid (3-NP) has been found to effectively produce HD-like symptoms. Amaranthus viridis Linn (HAEAV), popularly known in Chauraiya Hindi, may act as a neuroprotective agent vitro andin vivo. We evaluated the hypothesis that hydro-ethanolic extract of could prevent behavioral and oxidative a...

Physical therapies and exercise may have potential as a disease modifying agent in Huntington's disease (HD) and in recent years, there have been several small scale feasibility studies that have shown benefit as a result of physical interventions. When evaluating complex physical interventions, a phased approach using mixed methodology designs that report specific intervention components, adhe...

huntington’s disease (hd) is an inherited neurodegenerative disorder characterized by chorea and progressive dementia. the mutation causing the disease has been identified as an unstable expansion of a tri-nucleotide (cag) n at the 5 end of the it 15 gene on chromosome 4. we analyzed the distribution of cag repeats in 66 iranian patients belonging to 66 unrelated families. we found one expanded...
