This condition differs from Alzheimer's disease, where cognitive dysfunction is caused by amyloid beta plaques blocking neuron connectivity. In vascular dementia, obstructions in blood vessels lead to brain cell damage.
A study by University of Oxford scientists, published in the journal Circulation Research, marks a significant step in the fight against dementia. Dr. Praveen Gupta, principal director of neurology at Fortis Gurgaon, told TOI that these findings could be crucial in developing treatments for dementia. However, he emphasized the need for larger studies to confirm sildenafil's effectiveness before it could be adopted as a standard treatment.
High Prevalence in India
In India, the burden of vascular cognitive impairment and dementia is substantial, with about 5.3 million dementia patients, 40%
