The term âdementiaâ is used to describe a set of symptoms that can include memory loss, difficulty thinking, problem solving, or issues with language. Dementia is caused by damage to the brain cells, and because Alzheimer's is a disease that destroys the brain, it is one of the most common causes of dementia.
Most spider bites cause minor swelling, inflammation, and itching. However, bites from poisonous spiders can cause more severe reactions. Black widow bites affect the nervous system. The bite from a black widow may go unnoticed or may feel like a pinprick.
TREATMENT OF BITES: Spider mite bites rarely need treatment, but people who are allergic to mites may experience more itching and swelling than usual. If affected areas feel hot to the touch, apply a cold compress to reduce swelling. Oral antihistamines and cortisone ointments may also be helpful.
