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.
The most common symptoms of pneumonia include cough, fever, shaking chills, and shortness of breath. It can also cause other symptoms, such as a headache, loss of appetite, fatigue, sweating, nausea and vomiting, muscle pain, and chest pain when breathing deeply or coughing.
