Why tremors arise. A new scientific explanation
In early September 2024, researchers at Singapore's National Institute of Neurology presented the results of a new study -- they identified for the first time in the world how gene variations cause changes in the brain associated with essential tremor -- a common condition that causes uncontrolled hand tremors, such as writing or holding objects.
The researchers used MRI scans of the brain and genetic data from more than 33,000 adults from a base from UK Biobank. As a result, the team was able to identify a set of genes that are associated with thinning of the cortex (the outer region of the brain) and a decrease in cerebellar volume, which is involved in maintaining balance and ensuring accurate movements. The study also revealed how these genetic variations affect the brain at the cellular level. Such data are particularly important because they may be the basis for identifying new potential drug targets for tremor treatment.
 | Usually, the body is able to get rid of defective proteins, but sometimes the "quality control" system fails, which leads to changes in the brain. Such changes can disrupt cell functioning and signaling along a key neural pathway between the cerebellum, thalamus and motor cortex, leading to uncontrolled hand shaking, explained Dr. Thomas Welton, the team's principal investigator. |  |
Researchers are continuing to work on brain scans and assessing genetic data from Singaporeans who have been diagnosed with essential tremor. This additional research will help identify possible ethnic differences and their impact on brain development, which is important for the development of new treatments for tremors.[1]
Gloves for people with Parkinson are presented. They help take cups and write
In early January 2024, GyroGear announced GyroGlove smart gloves designed specifically for people with tremor and Parkinson's disease. The device allows you to stabilize your hands, which helps you write, take cups of drinks and perform other actions, such as fastening buttons. Read more here.
2023: Russia has developed a neurostimulator against tremor - it does not need to be implanted into the patient's body
The Far Eastern University (FEFU) created and tested the first Russian anti-transplant neurostimulator, which does not require implantation into the patient's body. The university spoke about the new development in November 2023. Read more here.
2022: Out is a system that, under MRI control, treats tremors on both sides of the body
On December 20, 2022, Insightec announced the launch of the Exablate Neuro system for the treatment of essential tremor. Read more here
