Washington, October 28 (QNA) - Researchers at Weill Cornell Medicine have found that MRI-guided focused ultrasound can ease Parkinson's motor symptoms, including tremors, stiffness and slow movement, without open-brain surgery. Published in The Lancet Neurology, the study involved 54 patients.

Among those treated on both sides of the brain in stages at least six months apart, 86 percent reported improvement three months after the second treatment, while 62 percent were satisfied with the procedure.

The technique targets abnormal nerve activity using focused ultrasound, with MRI guiding treatment and monitoring temperature.

Researchers said bilateral treatment may benefit selected patients, stressing the need to assess the initial response before treating the other side.

The technique offers an additional option for patients whose symptoms are inadequately controlled by medication, although individual benefits and risks require specialist assessment.

Parkinson's is a progressive neurological disorder involving the loss of dopamine-producing brain cells, causing movement difficulties and balance problems. (QNA)
