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.
Hepatitis B
Hepatitis B is an infection of the liver caused by hepatitis B virus. It can be short-term or become chronic and cause ongoing liver inflammation. Some people have few or no symptoms, while others develop fatigue, nausea, abdominal discomfort, dark urine, jaundice, or loss of appetite. Chronic hepatitis B can cause liver scarring, cirrhosis, liver failure, or liver cancer.

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.
Hepatitis B
Hepatitis B is diagnosed with blood tests that detect hepatitis B surface antigen, antibodies, and other markers of infection. Additional blood tests can assess liver inflammation and function. Testing can help determine whether an infection is acute, chronic, or resolved and whether a person has immunity. Imaging or other liver assessments may be recommended when chronic infection has caused or may have caused liver damage.

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.
Hepatitis B
Hepatitis B can be prevented effectively through vaccination. Avoiding contact with infected blood and body fluids, not sharing needles or injection equipment, practicing safer sex, and using sterile medical and tattoo equipment reduce transmission risk. Pregnant people should be tested so that appropriate measures can be taken to protect newborns when the mother has hepatitis B. People with known infection should receive appropriate medical monitoring.

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.
Hepatitis B
Risk factors include being born to a person with hepatitis B, unprotected sex with an infected person, sharing needles or injection equipment, occupational exposure to infected blood, and living in or frequently traveling to areas where hepatitis B is common. People receiving certain types of medical treatment or dialysis may also have increased exposure risk. Household exposure to infected blood or contaminated personal items can also transmit the virus.
