Overview

Influenza
Influenza is a contagious respiratory illness caused by influenza viruses. It commonly develops suddenly and may cause fever, chills, cough, sore throat, muscle aches, headache, and marked fatigue. Some people, particularly young children, may also experience vomiting or diarrhea. Most healthy people recover without serious complications, but influenza can lead to pneumonia and other severe problems in older adults, young children, pregnant people, and individuals with certain chronic conditions or weakened immunity. Seasonal vaccination and appropriate infection-control measures help reduce illness and transmission.
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.

Diagnosis

Influenza
Influenza can often be diagnosed clinically from symptoms and the pattern of illness during periods of active community transmission. Rapid influenza diagnostic tests may provide results quickly, although their ability to detect infection varies. Molecular tests, including rapid molecular assays and other laboratory methods, can provide more sensitive confirmation when testing is indicated. Testing is particularly useful when the result may affect treatment, infection-control decisions, or evaluation of people at higher risk of complications. The diagnosis should also consider other respiratory infections with similar symptoms.
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.

Prevention

Influenza
Annual influenza vaccination is an important measure for reducing the risk of influenza and its complications. Good hand hygiene, covering coughs and sneezes, improving indoor ventilation, and avoiding close contact with people who are ill can reduce transmission. People with influenza should stay home when sick when possible and follow local guidance about returning to normal activities. Higher-risk individuals should seek medical advice promptly when significant influenza symptoms develop because antiviral treatment may be most useful when started early.
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.

Risk Factors

Influenza
The risk of influenza is increased during periods when influenza viruses are circulating widely. Older adults, young children, pregnant people, and individuals with chronic heart, lung, kidney, metabolic, or neurological conditions may have a greater risk of serious complications. Weakened immunity can also increase risk. Close contact with infected people, crowded indoor environments, and inadequate ventilation can facilitate transmission. Lack of seasonal vaccination may increase susceptibility to circulating strains.
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.
