Which of the following best defines mental health disorders?

Mental health disorders are characterized by alterations in an individual's thinking, mood, or behavior, which can result in significant distress or impairment in social, occupational, or other areas of functioning. Mental health encompasses a range of conditions that impact the way an individual thinks and feels, which can affect how they interact with others and manage daily activities. These alterations can manifest as anxiety, depression, mood swings, or other psychological symptoms.

The other options do not accurately reflect the essence of mental health disorders. While physical impairments can affect daily life, they do not define mental health issues. Additionally, cognitive enhancements do not relate to the challenges presented by mental health disorders, and normal emotional variations are part of the human experience and not indicative of a disorder. Hence, the definition that focuses on changes in thinking, mood, or behavior is the most accurate and relevant way to describe mental health disorders.
