Huntington Disease

Posted on the 24 June 2023 by Sandra @shvong1

Huntington's disease (HD), a hereditary brain condition, degenerates nerve cells. Through huntingtin gene mutations, it is inherited. Although this is a neurological disorder, some features of disorder overlap with mental illness. This is the time to take opinion of psychiatrist.

Huntington's Disease Basics

Mutations in the huntingtin (HTT) gene, which generates huntingtin, cause HD. A mutant huntingtin protein accumulates in brain cells, causing damage and cell death.

Inheritance: HD is an autosomal dominant disorder, thus if one parent carries the defective gene, the child will have the disease. HD children have a 50% probability of inheriting the gene.

Huntington's disease symptoms normally arise in maturity, between 30 and 50, but they can occur at any age. The condition affects cognition and movement. Motor symptoms include chorea, coordination and balance issues, and gradual loss of voluntary movement control. Memory, focus, judgment, and reasoning are cognitive symptoms. Irritability, sadness, and social disengagement can also develop.

Huntington's illness worsens over time. Symptoms and development vary by person. The disease may worsen movement, speech, swallowing, and cognition.

Huntington's disease is diagnosed by genetic testing for the huntingtin gene mutation. Medical history, physical examination, neurological and psychiatric examinations, and imaging can help diagnose.

Huntington's disease is incurable. Treatment involves symptom management and support. Medications can reduce movement and psychological symptoms. Occupational, physical, and speech therapy may help sustain function. Support groups and counseling can help patients and their families cope with emotional and psychological issues.

Research and Future Prospects: HD mechanisms and treatments are being studied. Gene silencing, stem cell treatment, and neuroprotection are being investigated. Medical advances may lead to a cure.

Healthcare specialists and genetic counselors can provide tailored advice and support for Huntington's disease.

Symptoms

Huntington's disease include motor, cognitive, and mental symptoms. Note that symptoms and severity vary by person. Progressive illness worsens symptoms. Huntington's symptoms include:

Chorea, or involuntary movements, are common in HD patients. Facial, limb, and trunk motions can result. The sickness may worsen chorea.

HD can affect coordination, balance, and fine motor abilities. Walking, talking, and swallowing may be difficult. Movements can slow and stiffen.

Dystonia: Muscle contractions that twist or repeat cause dystonia.

Cognitive Symptoms

HD impairs memory, concentration, and reasoning. Planning, organizing, and decision-making may be tough.

Impaired executive function: Problem-solving, multitasking, and task-initiation and completion.

Slowed thought processes: Processing speed and mental flexibility may gradually deteriorate.

Psychiatric Symptoms

Depression: Many HD patients feel gloomy, despondent, and lose interest in formerly cherished activities.

HD patients can develop generalized anxiety, social anxiety, and obsessive-compulsive symptoms.

HD Can Cause Irritation, Anxiety, And Wrath.

Psychosis: Advanced disease can cause hallucinations, delusions, and psychotic symptoms.

Huntington's disease symptoms are prevalent, although each person's experience is different. Symptoms can also differ by age and development. Huntington's disease patients benefit from early discovery, medical management, and supportive care.

Causes

The huntingtin (HTT) gene on chromosome 4 causes HD. The mutation expands a gene CAG trinucleotide repeat sequence. Mutations expand the glutamine-coding CAG repeat.

The number of HTT gene CAG repeats impacts HD risk, onset age, and severity. HTT normally has 10-35 CAG repeats. HD patients have CAG repeat expansions over 36. CAG repeats accelerate illness onset and severity.

An aberrant huntingtin protein, harmful to brain neurons, is produced by CAG repeat expansion. Mutated huntingtin disrupts energy metabolism, protein folding, and intracellular transport, causing neuronal injury. Neurons in the basal ganglia and cerebral cortex degenerate with time.

Huntington's illness inherits autosomally. The mutant HTT gene from one sick parent gives a person a 50% risk of developing the condition, regardless of gender. Children of affected parents have a 50% chance of acquiring the mutant gene. Without the defective gene, a person cannot develop HD or pass it on.

HD can occur without a familial history in rare situations. Spontaneous HTT gene mutations during egg or sperm production cause these occurrences.

Treatment

Huntington's disease (HD) has no cure, thus therapy focuses on symptom management, supportive care, and quality of life. Multidisciplinary teams of healthcare professionals are usually used.

Tetrabenazine and deutetrabenazine reduce brain dopamine, helping HD chorea.

Antipsychotics: HD patients with psychosis may be prescribed antipsychotics to treat hallucinations, delusions, and other symptoms.

Antidepressants and anti-anxiety medications: HD patients often experience depression and anxiety.

Occupational/Physical Therapy

Occupational therapy can assist HD patients maintain independence and adjust to everyday changes. They may advise house changes, assistive gadgets, and motor skill improvement strategies.

Physical therapy: Physical therapists help with balance, gait, and mobility. They may recommend stretching, exercises, and other physical therapy.

speaking and Swallowing Therapy: Speech-language pathologists aid HD patients with speaking, voice projection, and swallowing. They may teach swallowing and communication activities.

Dysphagia can develop with HD. Swallowing therapists advise on safe swallowing, food consistency, and adaptation.

Psychological Support

Psychotherapy: Psychotherapy, including cognitive-behavioral therapy (CBT), can assist HD patients and their families manage emotional, psychological, and social issues. It supports, addresses worries, and improves well-being.

Support groups: HD support groups provide emotional support, knowledge, and community.

Palliative Care

Palliative care: Palliative treatment helps HD patients feel better. It involves symptom management, emotional and spiritual support, and disease progression.

HD carers need help. Supportive programs, respite care, and everyday caregiving assistance can aid HD caregivers.

HD patients and their families should collaborate with HD specialists. Each patient's symptoms and needs should guide treatment. Staying current on research and participating in clinical trials may also help us comprehend HD and access new treatments.

Conclusion

Huntington's disease, a genetic illness, causes brain nerve cell degeneration. A huntingtin gene mutation produces an aberrant huntingtin protein. Each kid of an affected parent has a 50% chance of acquiring the mutant gene because HD is autosomal dominant.

It has motor, cognitive, and mental symptoms. Chorea, coordination, and voluntary movement issues are motor symptoms. Cognitive symptoms affect memory, attention, and executive skills. Depression, anxiety, irritability, and psychosis are psychiatric symptoms.

Huntington's disease has no cure, therefore therapy focuses on symptom management and support. Medications can manage movement and psychological symptoms, while occupational, physical, and speech treatments can help maintain function. Individuals and their families need psychological support, therapy, and support groups to cope with the disease's emotional and social obstacles.

Research into Huntington's disease and potential treatments continues. Early detection, medical management, and a multidisciplinary approach can help HD patients live better. Individuals and their families must collaborate with disease-management experts to create tailored treatment programs and access support and services.
