What is the term for semi convulsive twitches that often occur before death?

The term that accurately describes semi convulsive twitches occurring before death is known as "agonal twitch." This phenomenon is typically observed in the moments leading up to death, as the body undergoes its final physiological changes. Agonal twitches can be a response to the disturbance in the body’s systems, particularly in the brain and muscles, as they respond to decreasing oxygen levels and the consequential physiological stress.

Understanding this process is important in the context of end-of-life care and the physiological changes associated with dying, which can be distressing for observers. Recognizing agonal twitches as a natural part of the dying process can help caregivers provide comfort and support to both the individual and their loved ones during this difficult time.
