Huntington's disease (HD), also known as Huntington's chorea, is an incurable neurodegenerative disease [7] that is mostly inherited. [8] The earliest symptoms are often subtle problems with mood or mental/psychiatric abilities. [9] [1] A general lack of coordination and an unsteady gait often follow. [2]
Huntington's disease is a neurodegenerative disease caused by mutations in a single gene HTT, that encodes for huntingtin protein. Symptoms include cognitive impairment and this usually declines further into dementia. [86] The first main symptoms of Huntington's disease often include: difficulty concentrating; memory lapses
Huntingtin (Htt) is the protein coded for in humans by the HTT gene, also known as the IT15 ("interesting transcript 15") gene. [5] Mutated HTT is the cause of Huntington's disease (HD), and has been investigated for this role and also for its involvement in long-term memory storage.
Although Alzheimer's disease accounts for the majority of cases of neurocognitive disorders, there are various medical conditions that affect mental functions such as memory, thinking, and the ability to reason, including frontotemporal degeneration, Huntington's disease, dementia with Lewy bodies, traumatic brain injury (TBI), Parkinson's ...
Neurodegenerative diseases include amyotrophic lateral sclerosis, multiple sclerosis, Parkinson's disease, Alzheimer's disease, Huntington's disease, multiple system atrophy, tauopathies, and prion diseases. Neurodegeneration can be found in the brain at many different levels of neuronal circuitry, ranging from molecular to systemic. [4]
Diseases such as progressive supranuclear palsy, Huntington's chorea and Parkinson's disease are different in many features from the other cortical dementias like Alzheimer's disease. Yet these patients present clinically with mild forgetfulness and slowed thought process along with abnormal movements and problems with motility.
The first signs of Huntington's Disease are generally subtle; those affected commonly note tics and twitching as well as unexplained fluctuations of mood. Clumsiness, depression and irritability are noted. What begins as a slurring and slowing of speech eventually leads to difficulty communicating, reliance on a wheelchair, or confinement to a bed.
Huntington's disease is a hereditary disease that causes defects in behavior, cognition, and uncontrolled rapid, jerky movements. [1] Huntington's disease stems from a defect that consists of an expanded CAG repeat in the huntingtin gene (HTT) located on the short arm p of chromosome 4. [7]
