Taking good care of your teeth may be linked to better brain health, according to a study published in the July 5, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study found that gum disease and tooth loss were linked to brain shrinkage in the hippocampus, which plays a role in memory and Alzheimer’s disease. The study does not prove that gum disease or tooth loss causes Alzheimer’s disease; it only shows an association.

A recently-published study led by Prof. Einat Levy-Gigi, from Bar-Ilan University, examined for the first time the interactive effect of exposure to stress in the school setting and cognitive flexibility on the tendency to develop post-traumatic symptoms among education and teaching staff. One hundred fifty education and teaching personnel (85% women and 15% men with an average age of 43 and average teaching experience of 13 years) volunteered to participate in the study and underwent an assessment of their exposure to stress, their cognitive flexibility, their ability to cope and their level of post-traumatic symptoms.

Odontoid fractures—those occurring in the second cervical vertebra—are common in elderly patients after a low-energy fall. However, whether the initial treatment should be surgical or nonoperative still isn’t known. Previous studies haven’t accounted for differences in injury severity, or the presence or absence of neurologic impairment, which can affect patients’ results.

Glioblastoma cells are poised near a “critical point” of order and disorder — meaning, the cells possess some form of large-scale coordination throughout the whole tumor that allows them to respond in practical unison to attempts to kill tumor cells, such as chemotherapy or radiation, a study suggests. Researchers say disrupting the large-scale organization of brain tumors may result in more powerful ways to treat and one day eliminate brain tumors.

A soft robotic glove is lending a “hand” and providing hope to piano players who have suffered a disabling stroke. Combining flexible tactile sensors, soft actuators and AI, this robotic glove is the first to “feel” the difference between correct and incorrect versions of the same song and to combine these features into a single hand exoskeleton. Unlike prior exoskeletons, this new technology provides precise force and guidance in recovering the fine finger movements required for piano playing and other complex tasks.

Co-existing use of alcohol and cannabis can lead to negative outcomes such as the development of a substance-use disorder, poor academic and occupational performance, and psychiatric disorders when compared to use of either drug alone. New research that examines simultaneous alcohol/cannabis use has found higher levels of drinking after 18 months. These results and others will be shared at the 46th annual scientific meeting of the Research Society on Alcohol (RSA) in Bellevue, Washington.
