Parkinson disease, late-onset

Parkinsonism refers to all clinical states characterized by tremor, muscle rigidity, slowed movement (bradykinesia) and often postural instability. Parkinson disease is the primary and most common form of parkinsonism. Psychiatric manifestations, which include depression and visual hallucinations, are common but not uniformly present. Dementia eventually occurs in at least 20% of cases. The most common sporadic form of Parkinson disease manifests around age 60; however, young-onset and even juvenile presentations are seen. [from GeneReviews]

Parkinsonism

Characteristic neurologic anomaly resulting form degeneration of dopamine-generating cells in the substantia nigra, a region of the midbrain, characterized clinically by shaking, rigidity, slowness of movement and difficulty with walking and gait. [from HPO]

Disease or Syndrome
11.

Dopamine

A monoamine compound with positive inotropic activity. Dopamine is a naturally occurring catecholamine formed by decarboxylation of dehydroxyphenylalanine and a precursor of norepinephrine and epinephrine. Dopamine binds to alpha-1 and beta-1 adrenergic receptors. Mediated through myocardial beta-1 adrenergic receptors, dopamine increase heart rate and force, thereby increasing cardiac output. Alpha-1 adrenergic receptor stimulation on vascular smooth muscle, leads to vasoconstriction and results in an increase in systemic vascular resistance. Stimulation of dopaminergic receptors in renal vasculature, leads to renal blood vessel dilation, and an increase in glomerular filtration rate, renal blood flow, sodium excretion, and urine output. [from NCI]

Concept ID:
C0085584
Disease or Syndrome

Oxidopamine

A neurotransmitter analogue that depletes noradrenergic stores in nerve endings and induces a reduction of dopamine levels in the brain. Its mechanism of action is related to the production of cytolytic free-radicals. [from MeSH]

Disorder of nervous system

The brain, spinal cord, and nerves make up the nervous system. Together they control all the workings of the body. When something goes wrong with a part of your nervous system, you can have trouble moving, speaking, swallowing, breathing, or learning. You can also have problems with your memory, senses, or mood. There are more than 600 neurologic diseases. Major types include. - Diseases caused by faulty genes, such as Huntington's disease and muscular dystrophy. - Problems with the way the nervous system develops, such as spina bifida. - Degenerative diseases, where nerve cells are damaged or die, such as Parkinson's disease and Alzheimer's disease. - Diseases of the blood vessels that supply the brain, such as stroke. - Injuries to the spinal cord and brain. - Seizure disorders, such as epilepsy . - Cancer, such as brain tumors. - infections, such as meningitis.  [from MedlinePlus]

Disorder of brain

The brain is the control center of the body. It controls thoughts, memory, speech, and movement. It regulates the function of many organs. When the brain is healthy, it works quickly and automatically. However, when problems occur, the results can be devastating. . Inflammation in the brain can lead to problems such as vision loss, weakness and paralysis. Loss of brain cells, which happens if you suffer a stroke, can affect your ability to think clearly. Brain tumors can also press on nerves and affect brain function. Some brain diseases are genetic. And we do not know what causes some brain diseases, such as Alzheimer's disease. The symptoms of brain diseases vary widely depending on the specific problem. In some cases, damage is permanent. In other cases, treatments such as surgery, medicines, or physical therapy can correct the source of the problem or improve symptoms. .  [from MedlinePlus]

Movement disorders

Imagine if parts of your body moved when you didn't want them to. If you have a movement disorder, you experience these kinds of impaired movement. Dyskinesia is abnormal uncontrolled movement and is a common symptom of many movement disorders. Tremors are a type of dyskinesia. . Nerve diseases cause many movement disorders, such as Parkinson's disease. Other causes include injuries, autoimmune diseases, infections and certain medicines. Many movement disorders are inherited, which means they run in families. Treatment varies by disorder. Medicine can cure some disorders. Others get better when an underlying disease is treated. Often, however, there is no cure. In that case, the goal of treatment is to improve symptoms and relieve pain.  [from MedlinePlus]
