How chronic stress causes brain damage

Chronic stress causes autophagy in adult hippocampal neural stem cells. This results in a decline of hippocampal neurogenesis. Cognitive deficits and mood disorders that arise as a result of chronic stress are a result of autophagic death of hippocampal neural stem cells.

Taking out the Protein Garbage Becomes More Difficult as Neurons Age

In aging mice, the number of autophagosomes is significantly decreased, and pronounced defects in the structure of autophagosomes increased. Turning on the WIPI2B protein restores autophagosome formation in aged neurons.

Blood pressure drug shows promise for treating Parkinson’s and dementia in animal study

Felodipine, a common hypertension medication, induces autophagy and clears aggregate-prone proteins associated with neurodegenerative diseases. The study reveals the drug clears mutant alpha-synuclein in the brains of mice at plasma concentrations to those seen in humans taking the medication. Felodipine appears to have some neuroprotective properties in mouse models of neurodegenerative diseases.
