Hippocampus News and Research

RSS

The hippocampus is a part of the forebrain, located in the medial temporal lobe. It belongs to the limbic system and plays major roles in short term memory and spatial navigation. Humans and other mammals have two hippocampi, one in each side of the brain.

Social isolation linked to brain volume loss in older adults

Older people who have little social contact with others may be more likely to have loss of overall brain volume, and in areas of the brain affected by dementia, than people with more frequent social contact, according to a study published in the July 12, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Unlocking the fountain of youth: Diet and exercise have a remarkable impact on cognition in older adults

The aim of non-pharmacologic interventions for brain health is to preserve cognitive function and safeguard brain structure. This review explores various diets (MeDi, DASH, MIND, ketogenic), exercise approaches (endurance, resistance, yoga, HIIT), and highlights the need for further research to uncover the underlying mechanisms.
