Alzheimer’s disease killed 74,632 people in 2007. The condition is the most common form of dementia in older adults, according to the CDC. The disease is characterized by problems with memory, language and thinking and can make it difficult to carry out daily activities.
Alzheimer’s typically begins around age 60, and the risk of the disease increases with age. Those with a family history of Alzheimer’s or specific genetic traits are at risk for the condition. Reducing head trauma, keeping a healthy heart and maintaining a healthy weight may reduce your risk of the disease, according to the Alzheimer’s Association.
Accidents, or unintentional injuries, accounted for 123,706 deaths in 2007. Within this category, the most significant killers were car accidents , which caused 42,031 deaths; falls, which lead to 22,631 deaths; and poisonings, which killed 29,846 people.
Though accidents were the No. 5 cause of death among all age groups, motor vehicle accidents were the leading cause of death for those under 34 years old, according to the CDC. For those ages 35 to 74, unintentional poisonings, including drug overdoses, account for more deaths than car crashes. Falls are the leading cause of injury-related death among those 65 and older.
Chronic lower respiratory diseases
Chronic lower respiratory diseases, a group of diseases that affect the airways and lungs, were responsible for 127,924 deaths in 2007. The most lethal chronic lower respiratory disease is chronic obstructive pulmonary disease (COPD ), which includes chronic bronchitis and emphysema. Chronic bronchitis is characterized by swollen and narrow airways inside the lung while emphysema is caused by damaged lung air sacs. Both these conditions make breathing difficult.
Smoking is the main culprit behind COPD. Men who smoke are 12 times more likely to die of COPD than men who have never smoked, according to the CDC, and avoiding smoking and secondhand smoke can reduce the risk of this condition.
Stroke accounted for 135,952 deaths in 2007. A stroke occurs when the blood supply to an area of the brain is obstructed, causing brain cells to die, or when a brain blood vessel bursts, according to the CDC. It can lead to paralysis, speech difficulties and death.
Risk factors include high blood pressure, high cholesterol, heart disease, diabetes, being overweight or obese, drinking excessive amounts of alcohol and smoking. Men have a greater risk of stroke than women. Eating a healthy diet, exercising and maintain a healthy weight are activities that can reduce stroke risk, according to the CDC.
Cancer of all types was responsible for the deaths of more than 562,800 people in 2007. Cancer refers to uncontrolled cellular growth, which can occur in many different tissue types. The most common cancers in men are prostate cancer, lung cancer and colorectal cancer, according to the CDC.. The most common cancers in women are breast cancer , followed by lung and colorectal cancer. Lung cancer causes the most deaths among men and women, followed in women by breast cancer.
A combination of hereditary and lifestyle factors likely contribute to a person’s cancer risk. Quitting smoking may reduce the risk of several types of cancer , including lung and kidney cancer, according to the National Cancer Institute. There is also evidence that a diet rich in fruit and non-starchy vegetables may reduce the risk of mouth, esophagus and stomach cancers. Obesity has been linked to an increased risk of several cancers, including colorectal and endometrial cancer.
Heart disease was the No. 1 cause of death in the United States in 2007. It claimed 616,067 lives, about a quarter of all deaths in the United States. A number of conditions fall into the category of “heart disease,” including coronary artery disease — the most common type of heart disease — and problems with heart rhythm. Risk factors include obesity , smoking, high blood pressure , diabetes and high cholesterol, according to the CDC, and lowering your cholesterol and blood pressure may reduce your risk of dying from heart disease.
