There is no cure for Huntington's, but you can treat it symptomatically. In general, you will use anti-dopaminergic drugs.

Classically, ET (essential tremor) abates with alcohol consumption. This means that drinking alcohol can temporarily reduce the symptoms of essential tremor. However, it is important to note that this effect may vary from person to person, and excessive alcohol consumption can worsen the condition in the long run. The mechanism behind this phenomenon is not fully understood, but it is believed that alcohol affects certain neurotransmitters in the brain, leading to a temporary suppression of tremors. It is worth mentioning that alcohol should not be considered as a long-term treatment for essential tremor, and individuals should consult with a healthcare professional for appropriate management.

The correct answer is 4. The question asks for the chromosome where the mutation responsible for the disease is found. The answer "4" indicates that the mutation is located on chromosome 4. The alternative answer "Four" is simply the written form of the number 4.

This disease involves a trinucleotide repeat, meaning that a specific sequence of three nucleotides is repeated multiple times. The sequence involved in this disease is CAG.

The statement is false because ET (essential tremor) is not typically responsive to anti-PD (anti-parkinson's disease) drugs. Essential tremor is a neurological disorder characterized by involuntary shaking or trembling of certain parts of the body, usually the hands or arms. While anti-PD drugs are commonly used to manage Parkinson's disease, they are not effective in treating essential tremor. Different medications, such as beta blockers or anticonvulsants, are often prescribed to help manage the symptoms of essential tremor.

Autosomal Dominant inheritance means that the disease is caused by a mutation in one copy of a gene, and an affected individual has a 50% chance of passing the mutated gene to each of their children. This type of inheritance does not skip generations and can affect both males and females equally.

The four cardinal motor features/sx of Parkinson's Disease are postural instability (shuffling gait, stooped stance), bradykinesia, resting tremor (aka pill rolling tremor), and rigidity.

Amantadine is a drug that is currently used to treat Parkinson's disease (PD). However, it was previously used as an antimicrobial agent. This means that it was originally developed and used to combat microbial infections. Over time, researchers discovered that amantadine also had beneficial effects in treating the symptoms of PD, leading to its current use in this context.

At the onset of PD symptoms, approximately 80% of dopamine neurons are lost. This means that a significant majority of these neurons are already damaged or destroyed when the symptoms of Parkinson's disease first appear. This loss of dopamine neurons is a key factor in the development of the motor symptoms associated with PD, such as tremors, stiffness, and difficulty with movement. Understanding the extent of this neuronal loss helps to explain the severity of symptoms and guides treatment approaches aimed at increasing dopamine levels in the brain.

Imaging studies of her brain will show atrophy of the putamen and caudate. Atrophy refers to the shrinkage or loss of cells in a particular structure. The putamen and caudate are both part of the basal ganglia, which are important for motor control and coordination. Atrophy in these structures can lead to movement disorders such as Parkinson's disease or Huntington's disease. The other options listed, such as thalamus, cortex, and myelin, are not specifically mentioned as being affected by atrophy in this case.

Essential Tremor is the most common movement disorder. It is a neurological condition characterized by involuntary shaking or trembling of different parts of the body, most commonly the hands. The tremors can range from mild to severe and can affect daily activities such as writing, eating, or speaking. Essential Tremor is often hereditary and typically worsens over time. While it is not life-threatening, it can significantly impact a person's quality of life. Treatment options include medications, lifestyle changes, and in severe cases, surgical interventions.

The condition in question #8 is referred to as an action tremor. Action tremor is a type of tremor that occurs during voluntary movements and is often triggered or worsened by actions such as reaching for objects or performing fine motor tasks. This type of tremor is different from other types such as resting tremor, which occurs when the muscles are at rest.

Benzodiazepines, topiramate, propranolol, and primidone are typically used to treat essential tremor (ET). Benzodiazepines are a class of drugs that have sedative and muscle relaxant effects, which can help reduce tremors. Topiramate is an anticonvulsant medication that can also be effective in reducing tremors. Propranolol is a beta-blocker that can help control tremors by blocking the effects of adrenaline. Primidone is an anticonvulsant that can also be used to reduce tremors. These medications are commonly prescribed to manage the symptoms of ET and improve quality of life for individuals with this condition.

DBT (deep brain stimulation therapy) is a treatment method that involves the implantation of electrodes in specific areas of the brain to alleviate symptoms of certain neurological disorders. In the case of severe forms of essential tremor (ET), DBT can be used to target the Ventro-intermediate nucleus (VIM) of the thalamus. The VIM is a part of the central nervous system (CNS) and is involved in motor control. By stimulating the VIM, DBT can help regulate abnormal neural activity and reduce the tremors associated with ET.

MAO-B inhibitors are drugs that are thought to reduce the progression of Parkinson's disease. These drugs work by blocking the enzyme monoamine oxidase-B, which is responsible for breaking down dopamine in the brain. By inhibiting this enzyme, MAO-B inhibitors help to increase dopamine levels and improve motor symptoms in Parkinson's disease. Rasagaline is a specific MAO-B inhibitor that has been shown to be effective in slowing the progression of Parkinson's disease. Therefore, MAO-B inhibitors, including Rasagaline, are believed to be beneficial in reducing the progression of Parkinson's disease.

Dopamine agonists are a class of drugs used to treat Parkinson's disease. However, they have the unfortunate side effects of nausea/vomiting, hallucinations, psychosis, orthostatic hypotension, and psychosis. These side effects can be quite severe and can significantly impact the quality of life for individuals taking these medications.

The leading diagnosis for the 30-year-old woman with involuntary limb movements and personality changes, along with a family history of a neurologic disorder, is Huntington's Disease. This is supported by the presence of chorea (a characteristic symptom of Huntington's Disease) and the involvement of the caudate and putamen regions of the brain. Additionally, Huntington's Disease is known to be hereditary, autosomal dominant, and caused by a mutation on chromosome 4 with an expansion of CAG repeats.
