Final answer:
Option (D, E), A mental disorder is best defined as a prolonged problem that disrupts an individual's ability to cope in society. It encompasses a range of disorders, which can often be treated through various methods including medication and psychotherapy.
Step-by-step explanation:
What is a Mental Disorder?
A mental disorder is generally defined as a condition that significantly interferes with an individual's cognitive, emotional, or social abilities. The definition is broad and encompasses a variety of conditions that may affect a person's ability to function in daily life. One important aspect is the degree to which a mental disorder disrupts normal activities and the ability to cope in society, making option (B) 'A prolonged problem that interferes with an individual's ability to cope in society' the best match.
According to the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM), mental illnesses can include a wide range of conditions such as schizophrenia, major depression, bipolar disorder, anxiety disorders and phobias, and post-traumatic stress disorders (PTSD). These disorders can have a profound impact on an individual's life, affecting their thinking, mood, and relationships with others.
Mental disorders are not always permanent and incurable; they can often be treated with a combination of medication, psychotherapy, and other approaches. Therefore, options (D) and (E), which suggest that mental disorders can only be cured with medication or cannot be treated at all, are incorrect.
