POWER will identify the immune-metabolic and nutritional signatures associated with cognitive impairment in ageing and depression. A clinical trial investigating effects of diet, physical activity, and brain training on cognition and depressive symptoms will be conducted. The role of gut microbiota in mediating the beneficial effects of these interventions on cognitive outcomes, depressive symptoms, hippocampal neurogenesis and inflammation will then be conducted in an animal model.

Amyotrophic Lateral Sclerosis (ALS) is a fatal disease resulting in muscle weakness, paralysis and ultimately death, often within 2-3 years of symptom onset. These symptoms arise due to the loss of motor neurons from the brain and spinal cord. Treatment options are limited and have little impact on halting progression of the disease. This research project is aimed at developing and characterising new models of ALS that can be used to investigate how motor neurons degenerate in people living with ALS.

Parkinson’s disease is a debilitating disorder characterised by movement disorders, including tremor, cognitive dysfunction and non-motor impairments. It is the second most common age-related neurodegenerative disease with ~10 million sufferers worldwide, but the causes of tremor are poorly understood and treatment is wholly inadequate.

α-Synuclein (α-Syn) pathology is inextricably linked to the pathogenesis of Parkinson’s disease (PD), yet we have very limited understanding why specific neuronal populations are vulnerable to α-Syn-related PD pathology while others are much more resistant.
