New York residents may be interested to learn that, according to US Centers for Disease Control study, many Americans live with HIV for some time before getting diagnosed. What makes this study surprising is that this includes Americans who regularly visit their doctor.

Parents of teenagers in New York may want to be alert for complaints of sore throat from their kids. Serious sore throats that require a trip to the doctor could be caused a type of infection that many doctors don’t test for. If this infection goes untreated, it could lead to serious illness or even be fatal.

As cold and flu season comes to New York, people might also want to be on the lookout for symptoms of pneumonia. Pneumonia is a tricky disease that can be cured in a matter of weeks or, in some cases, can be fatal. For people who have lung cancer, pneumonia is a greater risk, and sometimes its symptoms can be missed because they can be mistaken for those associated with lung cancer. Symptoms that lung cancer and pneumonia share include persistent cough, shortness of breath, low energy and loss of appetite. Pneumonia can be caused by bacteria, fungi or a virus.

Throughout New York and the rest of the nation, Alzheimer’s disease is often misdiagnosed. A misdiagnosis can come in the form of a false positive, when doctors diagnose Alzheimer’s in patients who don’t have it, or a false negative, when doctors fail to detect the condition in a patient. A recent study published in Alzheimer’s & Dementia: Translation Research and Clinical Intervention reveals how psychosis complicates matters.
