Alzheimer’s and Parkinson’s are the two diseases that are often confused. However, they are not equals and should be treated differently. Patients with Alzheimer’s are usually elderly people who tend to slowly lose their memory; they have troubles recognizing their own relatives and can’t get back home safely. As for Parkinson’s, this illness can affect the human body at a younger age (read, a 40-year-old person is subject to it). The course of Parkinson’s is characterized by the involuntary trembling of one’s head, arms, and even tongue. As seen, the symptomatology of these two medical conditions has little in common. The medications that are deemed to fight with Alzheimer’s and Parkinson’s generally help the symptoms, but they are unable to cure the illness once and for all. It’s also worth mentioning that the Alzheimer’s – Parkinson’s therapy should be complex, meaning several drugs are meant to be taken in tandem.
