Millions of Americans were exposed to SARS-CoV-2, the virus that causes COVID-19, early in the pandemic but could not get diagnosed due to testing limitations. Many of those people developed a post-viral syndrome with symptoms similar to those of long COVID.
Only a small percentage of older adults who are in the early stages of Alzheimer’s disease meet the eligibility criteria to receive new monoclonal antibody treatments, drugs that target amyloid-ß plaques in the brain, an early sign of Alzheimer’s disease. The new research is published in the August 16, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. Clinical trial results for these drugs are only available in people in the early symptomatic stages of the disease, mild cognitive impairment or mild dementia due to Alzheimer’s disease.

A new study has found the transition from daylight saving time to standard time, when one hour is gained overnight, was associated with a brief increase in sleep disorders such as difficulty going to sleep or staying asleep, but there was no such association when an hour is lost in the change from standard time to daylight saving time. The study is published in the May 3, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. It also found a small difference in the amount of sleep people get depending on the season.

The study does not prove that living in disadvantaged neighborhoods causes memory and mental health problems. It only shows an association.
Vestibular schwannomas related to neurofibromatosis type 2 (NF2) are difficult to manage and are sometimes treated with a noninvasive option, stereotactic radiosurgery. A retrospective study conducted by an international, multicenter team found that stereotactic radiosurgery is effective for patients with these tumors while preserving serviceable hearing and not causing radiation-related tumor development or malignant transformation.

As estrogen levels fluctuate, a new study has found for female participants with migraine, their levels of the protein calcitonin gene-related peptide (CGRP) that plays a key role in starting the migraine process also fluctuate. The study is published in the February 22, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Researchers also found people who used only osmotic laxatives, a type of laxative that attracts water to the colon to soften stool, had an even greater risk. Other types of laxatives are bulk-forming, stool-softening, and stimulating. The study does not prove that laxatives cause dementia. It only shows an association.
