People with two common types of dementia, Lewy body dementia, and Alzheimer's disease, have unique walking patterns. The gait type signals subtle differences between the two disorders. Those with Lew body dementia change their steps more, varying the step time and length. They also display more asymmetry in movement compared to those with Alzheimer's disease. Researchers say gait could be a clinical biomarker for dementia subtypes.
A new, freely available computer platform creates a 3D model that brings together the macroscopic scale of tissue with the microscopic scale of individual cells. This allows the platform to realistically model brain cancer's mechanobiology while maintaining resolution power.
Studying auditory regions and brain pathways in humans, apes, and monkeys, researchers have identified a language pathway that interconnects the auditory cortex with frontal lobe regions. The language pathway in other primates suggests an evolutionary basis in auditory cognition and vocal communication.
Researchers propose an alternative mechanism to explain the link between hearing loss and dementia. The study sheds light on the role of the medial temporal lobe in auditory cognition.
The evolutionary development for both human and primate brains may have been similar for communication and memory.
Increased connectivity between the auditory cortex and motor control areas related to the mouth, face, and throat, could be a key feature in identifying misophonia, a condition marked by extreme reactions to "trigger sounds", such as other people chewing.
Increased ceramide levels in the brain may be a unique feature of all types of Lewy body dementias, including LBD associated with Parkinson's disease.
Researchers have developed a new system that comprises of a brain implant containing LEDs and gene therapy to modulate brain waves. The technology showed success in suppressing abnormal brain waves akin to those seen during an epileptic seizure.
