ABSTRACT
Background: A high dose of statin is used to obtain an intensive lipid-lowering in stroke patients, even in patients with normal lipid levels. There are limited data on effect of dosage of statins and functional outcome in stroke patients. Objectives: To compare serum cholesterol levels with severity of stroke measured by infarct volume. To compare functional outcome measured by mRS at day 90 with the dose of statin. Materials and Methods: This retrospective observational study was conducted in KMC Hospital Manipal, India between 2016 and 2018. Result: A total of 100 consecutive patients were included in the study, out of which 60 (60.0%) were males. Hyperlipidemia was present in 65 (65.0%) patients. On comparing the serum cholesterol levels with infarct volume using MRI, patients with low volume of ≤70 ml had higher mean serum total cholesterol concentration (223.83 mg/dl), whereas patients with high volume of >70 ml had low mean cholesterol level (218.70 mg/dl). The patients were divided into those who received low dose (≤20 mg) versus high dose (≥40 mg equivalent) of Atorvastatin. On comparing the mRS values at baseline and on day 90 with the dose of statins, patients who received a higher dosage had a statistically significant fall in mRS (p-0.045) at day 90. Conclusion: It was found that serum cholesterol levels were inversely related to the stroke severity. However, a higher the dose of statins resulted in better functional outcome and survival in post-stroke patients, possibly due to its neuroprotective effect.

Background and Aims: The scope of treatment in Alzheimer's Disease has widened in recent times with FDA approval of new drugs. This review looks at established treatments in AD as well as critically analyses the newer drugs available. Methods: Data in this review was gathered from PubMed; Google Scholar and MEDLINE from January-March 2023. Search words used were 'Alzheimer's Disease treatment' and 'Dementia treatment'. Results: Older time tested drugs like Acetyl Choline Receptor Inhibitors and NMDA Receptor antagonists remain the mainstay of pharmacological treatment in AD. Despite a lot of excitement about newer FDA approved drugs; we have to be cautious in their use. Aducanumab showed good reduction in CSF amyloid levels (biomarker of AD); but this did not necessarily translate into better clinical outcomes of patients. Conclusion: Despite the recent advances and approval of drugs in treatment of AD, we have to exhibit caution while prescribing these drugs. Even with a sound mechanism of action, these drugs do not always show improvement in clinical outcomes. More clinical trials are required for development of drugs in treatment of AD which explore various different mechanisms of action.
