Parkinson's disease symptoms evolve progressively, often beginning with a hardly observable tremor in just one hand. But while tremor may be the most identifiable sign of this disease, the disorder also commonly causes a slowing or freezing of movement. The face shows little to no expression and the arms don't swing while walking. Speech often becomes feeble and unintelligible. Symptoms tend to become worse as the disease advances. The symptoms of parkinson's disease diverge from one person to another. Early signs may be slight and can go ignored for longs periods of time. Symptoms usually start on one side of the body and usually remain worse on that side. Parkinson's disease signs and symptoms may include tremor, slowed motion, rigid muscles, impaired posture and balance, loss of automatic movements, speech changes and dementia, as well as several others. Many symptoms develop from the lack of a chemical messenger, called dopamine, in the brain. This happens when the specific brain cells that produce dopamine die or grow weak. But researchers are still not quite certain as to what sets this sequence of events in motion. Some conjecture that genetic mutations or environmental toxins may play a part in parkinson's disease. While there is no cure for parkinson's disease, many different types of medicines can treat its symptoms, such as Bromocriptine Mesylate, Exelon, Parlodel, and Rivastigmine Tartrate.
Alzheimer's disease is the most common agents that trigger dementia, the loss of intellectual and social abilities severe enough to interfere with daily functioning. In this disease, healthy brain tissue decays, leading to a uniform decline in memory and mental abilities. This condition is not a characteristic of normal aging, but the risk of the disorder increases with age. It may start with mild memory loss and confusion, but it eventually leads to irreversible mental impairment that destroys a person's ability to remember, reason, learn and imagine. Symptoms of this illness include memory loss, problems with abstract thinking, difficulty finding the right word, disorientation, loss of judgment, difficulty performing familiar tasks, personality changes (mood swings, distrust in others, increased stubbornness, social withdrawal, depression, anxiety, aggressiveness), among others. There is no specific factor that can be pinpointed as the cause of Alzheimer's disease. Instead, genetic, lifestyle and environmental factors are thought by scientists to trigger the onset of symptoms. While Alzheimer's disease causes are insufficiently understood, its effect on brain tissue is clear. Alzheimer's disease damages and kills brain cells, but it's not a dead-end road. This disorder is treatable with medicines like Carbidopa/Levodopa, Galantamine HBR, Razadine, Reminyl and Sinemet.
