Neurobiology of disease is that branch of neuroscience which deals with molecular, cellular, and systemic mechanisms of neurological disorder. This area research was done based upon how disruption in the normal functions of the brain leads to diseases like Alzheimer’s, Parkinson’s, MS, and ALS.

The neuroscience of disease stems from the dysfunction of neurodegenerative, neuroinflammatory, and neurovascular features. Neurodegeneration is as such indicative of the progressive loss of neurons structure and function-a hallmark of pathology in both Alzheimer’s and Parkinson’s diseases. Investigators are seeking mechanisms by which protein misfolding, oxidative stress, and mitochondrial dysfunction contribute to neuronal injury and death.

Neuroinflammation underlies the pathology of many neurological conditions-from MS to neurodegenerative diseases. It is now intuitive how immune cells and inflammatory cytokines might interact with neurons and what potential therapeutic targets could modulate disease progression and neurotoxicity.

Another highly sensitive area of attention in neurovascular dysfunction is blood-brain barrier breakdown and impaired cerebral blood flow. Such abnormalities may enhance the manifestation of the disease and can have conditions such as stroke and vascular dementia. Advances in neuroimaging, molecular genetics, and animal models create critical foundational building blocks for the basic neurobiology of disease. Techniques such as magnetic resonance imaging, positron emission tomography scans, and next-generation sequencing will allow for crucial probing of mechanisms of diseases and targeted therapies.
