LaVonne was one of the three patients who received the implant. While one of the other patients experienced similarly positive results, the other benefited significantly from the treatment.
These results are obviously not perfect, but with no cures in the pipeline, this type of treatment could show promise. However, other experts not involved in the study are more skeptical about such an interpretation of the results.
“This study has not shown that deep brain stimulation can slow down or improve cognitive and functional decline in Alzheimer’s disease,” Robert Howard, professor of Old Age Psychiatry at UCL, said in a statement. “It has shown (albeit in a small sample of three patients) that deep brain stimulation appears to be safe and well-tolerated in people with Alzheimer’s disease.”
