hyperexcitability

An abnormal state of increased sensitivity or responsiveness of a nerve, muscle, or organ to stimuli. / A psychological or behavioral state characterized by extreme emotional reactivity or an exaggerated response to external triggers.
Noun

This term is primarily used in clinical, neurological, and psychological contexts to describe a state of over-responsiveness. In a medical sense, it refers to a physiological malfunction where nerves or muscles fire too easily, often associated with pathology or toxicity. It carries a technical, objective tone and is rarely used in casual conversation.

When applied to psychology, the word describes a heightened state of emotional arousal or instability. It differs from general "excitement" by implying an abnormal or pathological level of reactivity that is often maladaptive or distressing to the individual.
