  Huntington's Disease Reviews: 2002
Motor disorders are another promising field for the therapeutic application of cannabinoid-related compounds, since the control of movement is one of the more relevant physiological roles of the endocannabinoid transmission in the brain.
Huntington's disease (HD) is an autosomal-dominant neurodegenerative disorder caused by a CAG trinucleotide repeat expansion in the HD gene.
These disorders seem to have defective oxidative phosphorylation as a common pathway in their pathogenesis and it may be that treatments designed to improve respiratory chain function may ameliorate the progression of these disorders.

Neurodegenerative complications of the urinary tract are present in about two-thirds of those with this disorder, and at least 60% have neurological symptoms such as ataxia (unbalanced walking) and startle myoclonus (an increased reaction to strong stimuli such as loud noises).
Seizure disorders are not uncommon (20%; median age 19 years), and may be caused by hypoglycemia (low blood sugar) or by the underlying neurodegeneration.
Although the physiologic mechanism of this disorder is still under investigation, symptoms are currently believed to occur through defects in nuclear and mitochondrial DNA that code for cell processes controlled by mitochondria, a cellular component responsible for many cell functions.

The silent epidemic is a term which refers to neurodegenerative disorders (such as Alzheimer's disease, sequelaes of stroke & Parkinson's disease) which plagues the majority of the geriatric population but is poorly recognized by the society due to their low public visibility and their social isolation.
Neurodegenerative disorders are complex with an onset that is followed by progressive deterioration.
The cause of neurodegenerative disorders lies not so much in the brain (though it is the brain that shows the symptoms) as in the kidney, which according to the theories of Traditional Chinese Medicine controls the bone and generates the marrow.

 Overview of Alzheimer's Disease and Parkinson's Disease
Neurodegenerative diseases evolve gradually, after a long period of normal brain function, due to progressive degeneration (i.e., nerve cell dysfunction and death) of specific brain regions.
Other movement disorders characterized by parkinsonism may be difficult to distinguish from classic PD on clinical grounds, but these so-called "Parkinson Plus" disorders can be separated from PD because of their unique neuropathological features.
Thus, AD and the disorders discussed here are examples of a large group of neurodegenerative diseases with a common mechanistic theme, i.e., the conversion of a normal brain protein into insoluble filamentous aggregates appears to play a critical role in the progressive degeneration of brain cells that cause the relentless loss of specific brain functions.

 Huntington's Disease
Huntington's Disease is a genetic, progressive, neurodegenerative disorder characterized by the gradual development of involuntary muscle movements affecting the hands, feet, face, and trunk and progressive deterioration of cognitive processes and memory (dementia).
In dominant disorders, a single copy of the disease gene (received from either the mother or father) will be expressed "dominating" the other normal gene and resulting in the appearance of the disease.
This disorder was described based on the experiences of one family and, except for lower frequency of eye-movement and the absence of seizures, it is similar to juvenile-onset Huntington’s Disease.

 Alzheimer's disease - Facts, Information, and Encyclopedia Reference article
Alzheimer's disease (AD), a neurodegenerative disorder, is the most common cause of dementia and characterised clinically by progressive intellectual deterioration together with declining activities of daily living and neuropsychiatric symptoms or behavioral changes.
As the disorder progresses, cognitive (intellectual) impairment extends to the domains of language (aphasia), coordinated movement (apraxia), recognition (agnosia) and those functions (such as decision-making and planning) closely related to the frontal lobe of the brain, reflecting extension of the underlying pathological process.
For most of the twentieth century, the diagnosis of Alzheimer's disease was reserved for individuals between the ages of 45-65 who developed symptoms of presenile dementia, which was considered to be a more or less normal outcome of the aging process.

 Ataxia with Vitamin E Deficiency - Quest Diagnostics Patient Health Library   (Site not responding. Last check: 2007-10-11)
Ataxia with vitamin E deficiency (AVED) is a rare inherited neurodegenerative disorder characterized by impaired ability to coordinate voluntary movements (ataxia) and disease of the peripheral nervous system (peripheral neuropathy).
Vitamin E deficiency often occurs secondary to disorders that impair the absorption of vitamin E from fat including liver disorders, disorders of fat metabolism, and disorders of bile secretion.
These disorders include cholestasis (a syndrome of various causes characterized by impaired bile secretion); cystic fibrosis (primarily a lung disorder that may also affect bile secretion); primary biliary cirrhosis (a liver disorder that results in cholestasis); and abetalipoproteinemia (a digestive disorder characterized by fat malabsorption).

 GENETIC SCREENING RECOMMENDED TO DETECT NEW NEURODEGENERATIVE DISORDER   (Site not responding. Last check: 2007-10-11)
Known as fragile X-associated tremor/ataxia syndrome, or FXTAS (pronounced fax-tass), the disorder affects older men who are carriers of a small mutation (premutation) in the same gene that causes fragile X syndrome, the most common cause of inherited mental retardation.
In 2001 the Hagerman team reported the first cases of FXTAS in men and suggested that the neurological dysfunctions could be due to the elevated levels of messenger RNA from the FMR1 gene mutation, which are consistently observed in the blood of premutation carriers.
This study was supported by grants from the National Institute of Neurological Disorders and Stroke and the National Institute of Child Health and Development, as well as general support from the UC Davis M.I.N.D. Institute.

 Genetic screening recommended to detect new neurodegenerative disorder in men over age 50
A team of researchers, led by physicians at the UC Davis M.I.N.D Institute, have discovered a new, progressive neurodegenerative disorder that predominantly affects men over age 50 and results in tremors, balance problems and dementia that become increasingly more severe with age.
A significant but currently unknown number of adults with these tremor and balance problems are being diagnosed as normal aging, Parkinson’s disease, senile dementia and Alzheimer’s disease when their condition may be accurately and easily identified with a standard DNA blood test ordered by their doctor.
"The disorder appears later in life in men who are generally healthy throughout childhood and early-to-mid-adulthood and have normal to above-average intelligence, yet is caused by a defect in a gene known to cause mental retardation usually diagnosed in early childhood."
