R40-R46: Symptoms and signs involving cognition, perception, emotional state and behaviour
R45: Symptoms and signs involving emotional state
Symptoms and signs involving the emotional state is a group of conditions where a person's emotional wellbeing is adversely affected. Such conditions may have various causes, including mental health disorders, stress, trauma, physical health problems, or certain medications. Symptoms often involve changes in mood or emotions, such as excessive crying, feelings of happiness or sadness that are out of proportion or inappropriate to the situation, irritability, anger, anxiety, or other emotional reactions. These symptoms can interfere with a person's daily life, relationships, or activities. Progression of these conditions depends on the underlying cause and how it is managed. The affected system in these conditions is primarily the nervous system, which includes the brain and nerves, as they control our emotions and emotional responses. These conditions do not transmit from person to person, but some causes, such as stress, can be influenced by environmental factors.
