In people with Parkinsonâs disease, specific nerve cells or neurons in the brain steadily break down or die. Most of the symptoms are caused by the loss of neurons that produce dopamine (chemical messengers in the brain).
The signs and symptoms of pneumonia vary from mild to severe. Many factors affect how serious pneumonia is, including the type of germ causing the infection and your age and overall health. People who have pneumonia may have other symptoms, including nausea (feeling sick to the stomach), vomiting, and diarrhea. Symptoms may vary in certain populations. Newborns and infants may not show any signs of the infection.
Pneumonia is a bacterial or viral infection of the lungs. Symptoms can include fever, chills, shortness of breath, coughing that produces phlegm, and chest pain. Pneumonia can usually be treated successfully at home with antibiotics but hospitalisation may be required in some cases.
