Introduction

Differences between individuals with bipolar disorder and healthy individuals include emotional fluctuations, cognitive performance, behavioral patterns, physiological responses, and social functioning. The core feature is extreme and recurrent mood shifts, accompanied by impairments in multiple functional areas. If persistent abnormal mood fluctuations affect daily life, prompt medical evaluation is recommended. In contrast, emotionally healthy individuals experience mood variations that are mild in intensity and can be self-regulated.

　　The differences between individuals with bipolar disorder and healthy individuals include emotional fluctuations, cognitive performance, behavioral patterns, physiological responses, and social functioning. The core feature is extreme and recurrent mood shifts, accompanied by impairments in multiple functional areas. If persistent emotional disturbances significantly affect daily life, timely medical consultation is recommended.

　　1. Emotional fluctuations: Healthy individuals experience mild emotional ups and downs that are well-regulated, whereas patients exhibit extreme excitement, overconfidence, talkativeness, and impulsivity during manic episodes, and prolonged sadness, hopelessness, and loss of interest during depressive episodes. These two states alternate repeatedly and may shift abruptly.

　　2. Cognitive performance: Healthy individuals maintain clear logical thinking and stable attention. During manic episodes, patients experience racing thoughts, poor concentration, and unrealistic optimism; during depressive episodes, they suffer from slowed thinking, reduced memory, and excessively low self-esteem. Cognitive functions fluctuate明显 with mood changes.

　　3. Behavioral patterns: Healthy individuals behave in socially appropriate ways with clear intentions, while patients during manic episodes may engage in reckless spending, indiscriminate socializing, or impulsive investments. During depressive episodes, they may isolate themselves, avoid social interactions, and show slowed movements, with some behaviors becoming disconnected from reality.

　　4. Physiological abnormalities: Healthy individuals have stable sleep and appetite, but patients may require little sleep for several days yet feel energetic during mania, along with increased appetite. During depression, they may suffer from insomnia or excessive sleeping, markedly reduced appetite, and physical symptoms such as palpitations and fatigue.

　　5. Social functioning: Healthy individuals can maintain stable relationships and perform normally at work or school. Patients, however, may experience interpersonal conflicts due to mood swings or withdraw from social activities due to depression, leading to significantly reduced efficiency in work or study and ongoing impairment in social and occupational functioning.

　　Treatment primarily involves mood stabilizers combined with cognitive-behavioral therapy to adjust thinking and behavior patterns. Management includes maintaining regular routines to avoid triggers, providing emotional support from family members, teaching patients to monitor their emotions, and encouraging participation in moderate social and rehabilitation activities to gradually restore social functioning.
