OBJECTIVE
To report a patient with Huntington's disease, confirmed by a molecular genetic study, presenting with clinical features suggesting Tourette's syndrome.
METHODS
A thirty-years male with personal antecedents of perinatal hypoxia, but normal development; and family history (paternal
Excitotoxicity plays a key role in ischemic neuronal death and is also one of the candidate mechanisms contributing to neurodegeneration in Huntington's disease (HD). Unexpectedly we have now found that transgenic mice expressing exon 1 of a mutant human HD gene (R6/1) are protected against global
BACKGROUND
Impairments in energy metabolism are implicated in Huntington's disease (HD) pathogenesis. Reduced levels of the mitochondrial enzyme succinate dehydrogenase (SDH), the main element of complex II, are observed post mortem in the brains of HD patients, and energy metabolism defects have
The excitotoxic hypothesis postulates a central role for the excitatory amino acids (EAAs) and their receptors in the neuronal damage that ensues cerebral ischemia-hypoxia and numerous other brain disorders. A major premise of the excitotoxic hypothesis is that neuronal protection can be achieved
Two patients with Huntington's disease (HD) and obsessive-compulsive disorder (OCD) are reported. The OCD was manifested by repetitive, stereotyped, complex, egodystonic behaviors that were disabling. These cases and other neurological syndromes with OCD (Gilles de la Tourette syndrome,
Material inhibiting migration of leukocytes in vitro from Huntington's disease patients, was obtained from human brain removed at autopsy. The active material was present in brainstem, basal ganglia and cerebellum but not in cerebral cortex. It could be recovered at autopsy up to 21.5 h after death,
Fetal striatal transplantation has emerged as a new therapeutic strategy in Huntington's disease (HD). Hypoxia is one of the microenvironmental stress conditions to which fetal tissue is exposed as soon as it is isolated and transplanted into the diseased host brain. Mechanisms that support
Neurodegeneration (NDG) is linked with the progressive loss of neural function with intellectual and/or motor impairment. Several diseases affecting older individuals, including Alzheimer's disease, Amyotrophic Lateral Sclerosis, Huntington's disease, Parkinson's disease, stroke, Multiple Sclerosis
Mitochondrial dysfunction is a central feature of a number of acute and chronic neurodegenerative conditions, but clinically approved therapeutic interventions are only just emerging. Here we demonstrate the potential clinical utility of low molecular weight inhibitors of the hypoxia inducible
Transcriptional deregulation and changes in mitochondrial bioenergetics, including pyruvate dehydrogenase (PDH) dysfunction, have been described in Huntington's disease (HD). We showed previously that the histone deacetylase inhibitors (HDACIs) trichostatin A and sodium butyrate (SB) ameliorate
Rhinacanthus nasutus (L.) Kurz (Acanthaceae) is an herb native to Thailand and Southeast Asia, known for its antioxidant properties. Hypoxia leads to an increase in reactive oxygen species in cells and is a leading cause of neuronal damage. Cell death caused by hypoxia has been linked with a number
Neurodegenerative diseases, generally characterized by a progressive deterioration in the structure and function of the brain, represent one of the world's major unsolved health problems. Therefore, it is urgent to discover therapeutic targets for the design of effective strategies for the treatment
Compromised mitochondrial function in neurons and glia has been observed in several neurodegenerative disorders, including Huntington's disease and Alzheimer's disease. Chemical/hypoxic preconditioning may afford protection against subsequently more severe oxidative damages. In this study, we tested
Hypoxia inducible factor-1 (HIF-1) is a transcriptional factor responsible for cellular and tissue adaption to low oxygen tension. HIF-1, a heterodimer consisting of a constitutively expressed β subunit and an oxygen-regulated α subunit, regulates a series of genes that participate in angiogenesis,
Neurologic conditions including stroke, Alzheimer disease, Parkinson disease, and Huntington disease are leading causes of death and long-term disability in the United States, and efforts to develop novel therapeutics for these conditions have historically had poor success in translating from bench
