Examples of Parkinson’s disease in the following topics:
-
- Alzheimer's disease and Parkinson's disease are both neurodegenerative disorders characterized by loss of nervous system functioning.
- In this section, Alzheimer's and Parkinson's disease will be discussed in more depth.
- Parkinson's disease is also a neurodegenerative disease.
- There is no cure for Parkinson's disease; treatment is focused on easing symptoms.
- Distinguish between the neurodegenerative disorders of Alzheimer's disease and Parkinson's disease
-
- Parkinson's disease is more common in older people, with most cases occurring after the age of 50; when it is seen in young adults, it is called young onset Parkinson's disease.
- A physician will diagnose Parkinson's disease from the medical history and a neurological examination.
- The neurocognitive impairments related to Parkinson's disease are diagnosed using the same criteria listed above for Alzheimer's disease.
- Parkinson's disease in most people is idiopathic (having no specific known cause).
- Summarize the diagnostic criteria, etiology, and treatment of Alzheimer's Disease and Parkinson's Disease
-
- The greatest source of insight into the functions of the basal ganglia has come from the study of two neurological disorders, Parkinson's disease and Huntington's disease.
- Parkinson's disease involves major loss of dopaminergic cells in the substantia nigra.
- Huntington's disease involves massive loss of medium spiny neurons in the striatum.
- The symptoms of the two diseases are virtually opposite: Parkinson's disease is characterized by a gradual loss of the ability to initiate movement, whereas Huntington's disease is characterized by an inability to prevent parts of the body from moving unintentionally.
- In Parkinson's disease, the ability to execute the components of movement is not greatly affected, but motivational factors such as hunger fail to cause movements to be initiated or switched at the proper times.
-
- An example of a hypokinetic basal ganglia disease is Parkinsonism.
- An example of a hyperkinetic basal ganglia disease is Huntington's Disease.
- The muscle rigidity, tremor at rest, and slowness in initiation and execution of movement that are the cardinal motor symptoms of Parkinson's disease, which is a hypokinetic disorder.
- Other motor deficits and common non-motor features of Parkinson's, such as autonomic dysfunction, cognitive impairment, and gait/balance difficulties, are thought to result from widespread progressive pathological changes commencing in the lower brain stem and ascending to the midbrain, amygdala, thalamus, and ultimately the cerebral cortex.
- Dystonia can occur as a hyperkinetic disorder or as a side effect of hypokinetic disorders such as Parkinson's disease.
-
- Thus, this type of fungus can also result in diseases within livestock.
- These drugs include those that promote vasoconstriction for treating migraines and Parkinson's disease.
-
- Rigidity has two main forms—"leadpipe" rigidity is stiffness of the muscle, maintained throughout the entire range of movement; "cogwheel" rigidity, typical of Parkinson's disease, is the combination of rigidity with tremors, producing spastic movements.
- Hypotonia can result from several diseases and disorders affecting motor control.
-
- Disorders like multiple sclerosis, spina bifida, Parkinson's disease, strokes, and spinal cord injury can all interfere with nerve function of the bladder.
-
- ., Parkinson's disease, motor neuron disease); then etiological reasons for the problem are then determined (e.g., inflammation).
- For example, vascular disorders (such as strokes) occur over minutes or hours, whereas chronic disorders (such as Alzheimer's disease) occur over a matter of years .
- Intracranial pressure is roughly estimated by fundoscopy; this also enables assessment for microvascular disease.
- Rigidity-Cogwheeling (abnormal tone suggestive of Parkinson's disease), Gegenhalten (resistance to passive change, where the strength of antagonist muscles increases with increasing examiner force.
-
- The most notable are Parkinson's disease, which involves degeneration of the melanin-pigmented dopamine-producing cells in the substantia nigra pars compacta (SNc), and Huntington's disease, which primarily involves damage to the striatum.
- Basal ganglia dysfunction is also implicated in some other disorders of behavior control such as the Tourette's syndrome, ballismus (particularly hemibalismus), obsessive–compulsive disorder (OCD), and Wilson's disease (Hepatolenticular degeneration).
- With the exception of Wilson's disease and hemiballismus, the neuropathological mechanisms underlying diseases of ganglia such as Parkinsons' and Huntington's are not very well understood or are at best still developing theories.
-
- Parkinson's disease is the most common movement disorder of the nervous system.
- As the brain ages there are also some degenerative changes along with some diseases involving the sense organs that can alter vision, touch, smell, and taste.
- Dementia (from Latin de- "apart, away" + mens (genitive mentis) "mind") is the progressive decline in cognitive function due to damage or disease in the brain beyond what might be expected from normal aging.
- Symptoms of dementia can be classified as either reversible or irreversible depending upon the etiology of the disease.
- Alzheimer's disease (AD) is a neurodegenerative disease characterized by progressive cognitive deterioration together with declining activities of daily living and neuropsychiatric symptoms or behavioral changes .
