Closed-loop stimulation for Parkinson Disease

PGC may affect other organs that are close to the striatum, most notably the cardiovascular or gastrointestinal systems. These are discussed with the possible links of PGC to Parkinson disease, and a model of how PGC may cause Parkinson disease is proposed as well.

Many medications are used to treat Parkinson's disease, but medications should be reserved for those who respond well to them, or for those who are intolerant of other therapies. Most patients require both pharmacological and nonpharmacological interventions on the basis of age, symptoms, and other factors. summary:

Signs of parkinson disease included tremor, bradykinesia and dysdiadochokinesia. There also may be changes in cognitive function and motivation in later disease. Early motor manifestations are more predictable in PD.

Parkinson disease is a disorder of the nervous system characterized by motor symptoms, and sometimes nonspecific brain abnormalities (a-vascular or idiopathic), that may be life changing. One in 5000 people will develop Parkinson's at some point in their life.

The majority of patients with Parkinson's disease can be cured of the progressive condition and disability without the need to take dopamine replacement medication. In the UK, around 50% of the patients with Parkinson's disease are currently treated in this way.

The estimated prevalence of this condition among elderly Americans is more than 15 million with a considerable number of these cases unrecognized. Many of these people are not aware of their condition's symptoms; thus, many are at risk for not receiving proper treatment.

There remains considerable debate about the primary cause of PD. Current knowledge is insufficient to identify a single etiological agent(s) responsible for the neurodegeneration observed in PD. A combined effort and a combination of various fields which are all pertinent to PD-research should yield new knowledge to advance our understanding of PD pathogenesis.

The average age at which Parkinson's disease is diagnosed appears to be 60–70 years and the first symptom of the disease seems to be a resting tremor. This age coincides with the estimated decline in dopaminergic activity in the brain and the age when dopaminergic drugs such as levodopa become necessary. Moreover, the age of onset of levodopa is often advanced in Parkinson's disease. Thus, it is expected that the number of people with PD might increase because of the anticipated age of onset of levodopa.

Closed-loop stimulation is well tolerated as a treatment paradigm for PD. Commonly-reported therapy-related side effects are manageable in the majority of patients. These include nausea, insomnia, and tremor in the first weeks of therapy. Long-term closed-loop stimulation does not result in further increase in BMI and it does not affect triglycerides.

Closed-loop movement stimulation, using one-thumb stimulation of the oculomotor muscles to control movement, was well-tolerated over 3 months, without any short- or long-term adverse effects reported in our trial. More studies are needed to determine whether the technique is safe and beneficial in nonneurological conditions, and for longer periods. It would not be feasible to test it in people with a neurological impairment.

There have not been any new findings for Parkinson's disease so far. It is known that there is dopamine in the brain that helps to help [movement] in Parkinson's disease, but because there is no medication or therapy to [control] the dopamine, a problem for some sufferers of Parkinson's disease is movement disorders such as tremors, [bradykinesia, dyskinesia, and dysarthria]. The main [other] problem is with [gait] disorders such as unsteadiness and [slow] gait. The main way to cure the [gait] problems is through medication or a surgical procedure called Deep Brain Stimulation called DBS in deep to [control] the dopamine in the brain.
