Akinesia is a medical term used to describe the loss or impairment of the power of voluntary muscular action. It is a symptom that can manifest in a variety of neurological conditions. Akinesia is characterized by a significant difficulty in initiating and executing voluntary movements, even though muscle strength may be preserved. This is often perceived as a slowness or absence of movement.

Individuals experiencing akinesia may have trouble starting movements, such as getting out of a chair or taking the first step. They might also exhibit a lack of spontaneous gestures, facial expressions, and blinking, contributing to a masked or immobile appearance. The gait can be affected, leading to shuffling steps and a stooped posture. Akinesia is a core feature of Parkinson's disease, where it is often accompanied by tremor and rigidity. It can also be seen in other conditions like certain types of stroke, traumatic brain injury, and some neurodegenerative disorders.

The underlying cause of akinesia typically involves dysfunction in the basal ganglia, a group of subcortical nuclei in the brain that play a crucial role in motor control, planning, and execution. Damage or degeneration in these areas disrupts the intricate neural pathways responsible for initiating and modulating movement. Diagnosis often involves a thorough neurological examination and consideration of the patient's medical history. Treatment strategies focus on managing the underlying condition and may include medications like levodopa for Parkinson's disease, or therapies such as physical and occupational therapy to help improve motor function and compensate for the deficits.
