V: Mental and behavioural disorders
Mental and behavioural disorders are a wide range of conditions that affect a person's thoughts, emotions, and actions. They can result from a variety of causes, such as genetic factors, chemical imbalances in the brain, physical injuries, and stressful life events. These disorders can disrupt a person's daily life, making it difficult for them to work, maintain relationships, and take care of their own health. Common symptoms can include changes in mood, thought patterns, or behaviour; difficulty concentrating or making decisions; feelings of fear or distress; and changes in eating or sleeping habits. Some disorders progress slowly over time, while others may show sudden onset of symptoms. They can affect anyone, regardless of age, gender, or background. The impact of these disorders can range from mild to severe, with some requiring long-term care.
