Parkinson and metal contamination

People living near a steel plant or other source of manganese emissions have increased risk of developing Parkinson’s. One million Americans live with the degenerative disease, according to the Parkinson’s Disease Foundation. Farm pesticides increase the chance of developing...

Parkinson Disease

Parkinsonism is a clinical syndrome that encompasses four aspects cardinal bradicinecia (slowness and lack of movement), muscle rigidity, tremor at rest (usually killed during voluntary movements) and postural balance disorders generated gait disorders and falls to soil. The most...

Parkinsonism Drug

The diagnosis of Parkinson’s disease should not be sure until it is known in detail all drugs that the patient, consciously or inadvertently, come take at the time of the query. It is well known that neuroleptics (phenothiazines, butyrophenones)...

Signs and Symptoms of Parkinson’s Disease

Part of parkinsonian patients develops, over time, subcortical dementia. Although the diagnosis of Parkinson’s disease is largely clinical, can take account of hyposmia (may precede up to 20 years to your appearance), positron emission tomography showing decrease of dopamine...

Pathophysiology of Parkinson’s Disease

Since the caudate nucleus and putamen, there is a path to the black substance secreted by the inhibitory neurotransmitter GABA (gamma aminobutyric acid). In turn, a series of fibers originating in the substantia nigra send axons to the caudate...

Diagnosis of Parkinson’s Disease

It was James Parkinson who described the disease in 1817 under the name of paralysis agitans. “The etiology is unknown but pathophysiologically related to a deficiency of dopamine in the striatum, resulting from neuronal degeneration that mainly affects the...

Found two new genetic variants associated with Alzheimer

A multicenter study is published today in JAMA has identified two genes that may be risk factors for development of Alzheimer’s disease late onset, although not help quantify the risk in carriers of these alterations. Researchers at Boston University,...

Treatment for People with Alzheimer

The proper treatment of persons with Alzheimer’s disease is essential, even when suffering from memory loss. People with this condition miss events as a conversation or a joke, but the happy feelings associated with these moments may survive and...

Molecular relationship between gene regulation and synaptic parkin in Parkinson’s disease

A new study has been first discovered a molecular link between Parkinson’s disease and defects in nerve cell communication. The work, published in Molecular Cell, provides new insights into the mechanisms underlying Parkinson’s disease, which could lead to new...
