Question

Delirium is never normal and often indicates a usually serious, newly developed problem, especially in older people. People who have delirium need immediate medical attention. If the cause of delirium is identified and corrected quickly, delirium can usually be cured.

Because delirium is a temporary condition, determining how many people have it is difficult. Delirium affects 15 to 50% of hospitalized people.

Delirium may occur at any age but is more common among older people. Delirium is common among residents of nursing homes. When delirium occurs in younger people, it is usually due to drug use (prescription, over-the-counter, or recreational) or a life-threatening disorder.

Answer 1

Mental illnesses such as schizophrenia, major depression, and bipolar disorder have significant impacts on individuals' lives. Schizophrenia and depression involve disruptions in neurotransmitter systems and require ongoing treatment. Alzheimer's disease is a widespread form of dementia among the elderly, leading to substantial caregiving needs.

Step-by-step explanation:

Mental Illnesses and Their Impact

Mental illnesses, such as schizophrenia, major depression, and bipolar disorder can profoundly affect an individual's thinking, mood, and ability to relate to others. Schizophrenia, a condition affecting 1% of the U.S. population, is characterized by symptoms like hallucinations, delusions, and disorganized thinking. Treatment usually involves antipsychotic medications, but they are not a cure and patients often require lifelong medication. Major depression affects about 6.7% of U.S. adults yearly and involves severe mood changes and other symptoms persisting for more than two weeks. While the cause of depression is not fully understood, it is thought to involve neurotransmitter imbalances, and treatment takes time to be effective. Bipolar disorder, affecting roughly 2.6% of Americans, features extreme mood swings and can disrupt daily living.

Amongst the elderly, dementia, including Alzheimer's disease, is common, with conditions worsening with age. These cognitive impairments often require comprehensive management and care. The growing population of older adults means diseases like Alzheimer's will become increasingly prevalent, with impacts on healthcare systems and society.
