Recent research from Chinese scientists has introduced a promising surgical technique aimed at addressing Alzheimer’s disease, the leading cause of dementia. Alzheimer’s is characterized by the accumulation of amyloid plaques and neurofibrillary tangles in the brain, leading to progressive cell death and cognitive decline.
According to the Mayo Clinic, Alzheimer's affects an estimated 60% to 70% of the over 55 million dementia patients worldwide. Currently, there is no cure, and the disease can ultimately lead to death.
The new technique was published in the journal 'General Psychiatry' and focuses on enhancing the removal of harmful proteins, such as beta-amyloid and tau, from the brain. This is achieved by connecting lymphatic vessels in the neck to the brain, facilitating the expulsion of waste proteins.
Initial results from the study indicated slight improvements in cognitive scores and daily functioning within weeks of the procedure. Brain scans also showed changes in protein levels. However, experts caution that these findings are preliminary and further extensive testing is needed.
Researchers acknowledge that while this technique does not cure Alzheimer’s or reverse brain damage, it could slow the progression of the disease, marking a significant step towards new possibilities in Alzheimer’s treatment.
Currently, medications like donanemab and lecanemab are used to slow the disease's progression. Experts believe that this new surgical technique may play a crucial role in future Alzheimer’s therapies.
Patients with Alzheimer’s often forget recent events and conversations, leading to increasing difficulties in daily tasks over time.
