The following submission statement was provided by /u/Apart_Shock:

>A new study published in the journal PLoS ONE has reported on the first human tests of an experimental therapy using sound and light to treat Alzheimer's disease (AD). The initial findings are promising, with the unique treatment leading to some neurological and cognitive improvements, but the small trial size means more study is needed before anyone can say this type of therapy works.
