Parkinson’s Disease
Parkinson’s Disease is a disorder of the central nervous system that affects movement, often including tremors.
Nerve cell damage in the brain causes dopamine levels to drop, leading to the symptoms of Parkinson’s.
Parkinson’s often starts with a tremor in one hand. Other symptoms are slow movement, stiffness, and loss of balance.
Medications can help control the symptoms of Parkinson’s.
Parkinson’s Disease is a progressive disease of the nervous system marked by tremor, muscular rigidity, and slow, imprecise movement, chiefly affecting middle-aged and elderly people. It is associated with degeneration of the basal ganglia of the brain and a deficiency of the neurotransmitter dopamine.
Symptoms:
Cluster Number:
Wiki Number: PW153
Diagnosis: Parkinson’s Disease (Very complex; please read the Wikipedia article.)
US Patients: 2-6X likelihood of dementia
World Patients: 6.2Mil&117,400 Deaths (2015)
Sex Ratio:
Age Onset: Over 60, usually; unless “early-onset Parkinson’s”
Brain Area: Cell deaths among the subantia nigra leads to dopamine deficits; Cells die from proteins into Lewy bodies in the neurons
Symptoms: tremor, slowness(bradykinesia), stiffness(excessive muscle contraction) and postural instability(10% fall weekly)
Progression: As it progresses, poor decision-making, less impulse control, impaired recall, less control of attention
Causes: genetics, injuries, pesticides;brain lesions from strokes;alpha-synuclein protein in the brain buildup; 50% have hallucinations
Medications: L-DOPA; deep brain stimulation by microelectrodes reduces muscular symptoms;
Therapies: Imaging by MRI, T2* and SW;, neuromelanin-MRI; Diffusion, MRI; PET; SPECT; DaTSCAN is the only FDA approved way to distinguish.

- Reduced striatal M4-cholinergic signaling following dopamine loss contributes to parkinsonian and l-DOPA-induced dyskinetic behaviorsby Beatriz E Nielsen on November 20, 2024
A dynamic equilibrium between dopamine and acetylcholine (ACh) is essential for striatal circuitry and motor function, as imbalances are associated with Parkinson's disease (PD) and levodopa-induced dyskinesia (LID). Conventional theories posit that cholinergic signaling is pathologically elevated in PD as a result of increased ACh release, which contributes to motor deficits. However, using approaches to measure receptor-mediated signaling, we found that, rather than the predicted enhancement,...
- Muscarinic receptors mediate motivation via preparatory neural activity in humansby John P Grogan on November 20, 2024
Motivation depends on dopamine, but might be modulated by acetylcholine which influences dopamine release in the striatum, and amplifies motivation in animal studies. A corresponding effect in humans would be important clinically, since anticholinergic drugs are frequently used in Parkinson's disease, a condition that can also disrupt motivation. Reward and dopamine make us more ready to respond, as indexed by reaction times (RT), and move faster, sometimes termed vigour. These effects may be...
- GenoTools: An Open-Source Python Package for Efficient Genotype Data Quality Control and Analysisby Dan Vitale on November 20, 2024
GenoTools, a Python package, streamlines population genetics research by integrating ancestry estimation, quality control (QC), and genome-wide association studies (GWAS) capabilities into efficient pipelines. By tracking samples, variants, and quality-specific measures throughout fully customizable pipelines, users can easily manage genetics data for large and small studies. GenoTools' "Ancestry" module renders highly accurate predictions, allowing for high-quality ancestry-specific studies,...
