Brain disorders may present symptoms such as headaches, trouble concentrating, seizures, memory issues and a distinct change in a person's normal behavior, according to Healthline. The exact symptoms of common brain disorders vary depending on the specific issue. If a brain disorder is suspected, the individual should seek medical attention for diagnosis and treatment.
Symptoms of a brain tumor depend on its type, size and location, states MedicineNet. Common symptoms include nausea, loss of balance, personality changes, numbness of the arms or legs, and changes in vision, speech or hearing. These symptoms can act up due to the pressure of a tumor on a nerve or when it blocks fluid flowing through and around the brain. Symptoms can also manifest if the brain swells up due to fluid buildup or when a tumor damages a part of the brain.
A patient experiencing brain trauma or a concussion can display several symptoms, such as slurred speech, blurred vision, clumsiness, sensitivity to light, and nausea or vomiting, according to WebMD.

Meningitis, a brain infection, brings symptoms such as confusion, neck stiffness, fever and headaches.
Encephalitis, an inflammation of the brain, can have mild to severe symptoms, reports MedlinePlus. Some patients experience flu-like symptoms that can be treated with rest and a pain reliever. Severe cases have symptoms that include drowsiness, seizures, severe headaches, vomiting and confusion.
