Abstract
Physical exercise is a cornerstone in the
management of many neurodegenerative disorders, such as Parkinson’s
disease, dementia,
and stroke. However, much of its beneficial effects
on improving motor functions and cognition as well as decreasing
neurodegeneration
and neuroinflammation are not yet well understood.
The obvious limitations of studying the protective mechanisms behind
exercise,
for example, brain plasticity and
neurodegeneration, could be overcome by generating novel animal models
of neurodegenerative
disorders. In this narrative review, we discuss the
beneficial effects of exercise performed in animal models of
neurodegenerative
disorders and how the results from animal studies
can be used in clinical settings. From preclinical studies, the positive
effects of exercise have been related to increased
levels of neurotrophic factors, elevated expression of anti-inflammatory
cytokines, and reduced levels of pro-inflammatory
cytokines and activated microglia. It is clear that parameters
influencing
the effect of exercise, such as intensity, still
remain to be investigated in animal studies in order to find the optimal
program that can be translated into exercise
interventions for patients with neurodegenerative diseases.
