Overview

Alzheimer Disease
Alzheimer disease is a progressive brain disorder that gradually damages memory, thinking, reasoning, and other cognitive abilities. As the disease progresses, a person may have increasing difficulty performing familiar everyday activities and may develop changes in communication, behavior, or judgment. The course varies between individuals, but symptoms generally become more significant over time as brain cells and connections are affected.
Encephalitis
Encephalitis is inflammation of the brain that can cause a serious illness affecting the nervous system. Symptoms may include fever, headache, confusion, unusual behavior, seizures, sensitivity to light, weakness, difficulty speaking, or loss of consciousness. Encephalitis can progress rapidly and may require urgent hospital treatment. Recovery varies according to the cause and severity of the inflammation.

Diagnosis

Alzheimer Disease
Diagnosis of Alzheimer disease involves evaluating memory, thinking, behavior, and the ability to perform everyday activities. Cognitive testing and neurological examination can help identify patterns of impairment. Brain imaging may be used to assess brain structure and exclude other causes of symptoms. Laboratory assessments may also be performed to identify potentially treatable conditions that can cause or worsen cognitive problems. The diagnosis is based on the overall clinical assessment and available test findings.
Encephalitis
Encephalitis is diagnosed using the symptoms, neurological examination, and tests designed to identify inflammation or infection of the brain. Evaluation may include brain imaging with CT or MRI, analysis of cerebrospinal fluid obtained by lumbar puncture, blood tests, and an electroencephalogram to assess brain electrical activity. Additional antibody or infectious-disease testing may be performed to determine the cause.

Prevention

Alzheimer Disease
There is no guaranteed method for preventing Alzheimer disease, but maintaining overall brain and cardiovascular health may be beneficial. Regular physical activity, a balanced diet, adequate sleep, and continued mental and social activity can support general health. Managing conditions such as high blood pressure, diabetes, and other cardiovascular risk factors is also important. Regular medical care can help identify and manage health problems that may affect cognitive function.
Encephalitis
Prevention depends on the cause. Recommended vaccinations can protect against some infections associated with encephalitis. Avoiding mosquito and tick bites through appropriate clothing, repellents, and environmental precautions can reduce exposure to certain infectious causes. Good hygiene can reduce transmission of some viruses. People should seek urgent medical attention for severe headache, confusion, seizures, or other rapidly developing neurological symptoms.

Risk Factors

Alzheimer Disease
Advanced age is the strongest known risk factor for Alzheimer disease. Having a family history of the condition or certain genetic factors can increase susceptibility. Cardiovascular conditions and factors that affect blood vessel health may also be associated with increased risk. Other potentially relevant factors include physical inactivity and some lifestyle-related health conditions. Having a risk factor does not mean that a person will necessarily develop Alzheimer disease.
Encephalitis
Risk depends on the underlying cause. Exposure to viruses and other infectious organisms can increase risk, including exposure through mosquito or tick bites or contact with infected people. Travel or residence in areas where certain mosquito- or tick-borne infections occur may also increase risk. People with certain immune-system disorders may be susceptible to autoimmune encephalitis. Age and overall health can influence the severity of illness.
