There may be several reasons for sudden excitement after depression:
1. Normal emotional fluctuations or external stimuli:
Excitement may be a normal emotional fluctuation caused by emotions such as happiness and excitement.
Some external factors such as environmental noise or food stimulation may also lead to high emotions.
2. Biochemical factors or drug effects:
Neurotransmitter imbalance, such as changes in the levels of neurotransmitters such as serotonin and norepinephrine in the brain, may affect emotional regulation.
Antidepressants may exert their effects by regulating neurotransmitter levels, and certain drugs such as selective serotonin reuptake inhibitors and tricyclic antidepressants may cause emotional arousal.
3. Psychological disorders or sleep disorders:
Bipolar disorder is a mental illness characterized by repeated emotional fluctuations, including two stages of depression and hyperactivity.
Sleep disorders may lead to disruptions in the biological clock, which in turn can affect emotional regulation and result in alternating periods of depression and excitement.
Depression accompanied by hyperthyroidism may also lead to emotional excitement, accompanied by symptoms such as protruding eyes, excessive sweating, and thick neck.
The above reasons are for reference only and cannot replace the diagnosis of professional doctors. When patients with depression experience symptoms of hyperactivity, they should seek medical attention in a timely manner so that doctors can conduct targeted assessments and treatments based on the specific situation.
