Dear Wallace - Please accept my sympathy for your loss. If a doctor has suggested that Janet died of "Parkinson's Sudden Death Syndrome," perhaps the doctor was merely describing an unexplained and unexpected death of an apparently healthy adult. In most States when a death occurs at home, unattended by a doctor, an autopsy is required. Is an autopsy scheduled for Janet? The results should be made available to you within 24 hrs. For Sudden Infant Death Syndrome researchers have developed a number of potential factors leading to laryngospasm, including apnea, positional narrowing of the airway, respiratory inflammation, hypoxia or transitory airway obstruction. These should all be ruled out before implicating the symptoms of Parkinson's. Because one can never be prepared for such a tragedy, aggravated by the need to investigate and find a reason for this death, you should seek the help of friends and support group members to deal with your expected grief. Do not try to deal with your terrible loss by yourself, there are people who care. Stephan 53/7
