Infectious diseases are disorders caused by organisms such as bacteria, viruses, fungi, or parasites.

They can be transmitted through direct contact with an infected person, animal, insect bites, or contaminated food and water.

Symptoms vary but often include fever, fatigue, muscle aches, cough, and digestive issues.

Diagnosis involves physical examinations, medical history review, and diagnostic tests such as blood tests, cultures, and imaging.

Treatments may include antibiotics, antivirals, antifungals, antiparasitics, and supportive care depending on the type of infection.

Deep brain stimulation surgery involves implanting a device that sends electrical impulses to specific brain areas to regulate abnormal activity and manage symptoms.

Preparation includes a thorough evaluation by a neurologist, imaging studies, and discussions about the procedure, risks, and benefits with your medical team.
