Alzheimer's could be detected early using a blood test

Researchers from the ARTFL-LEFFTDS Longitudinal Frontotemporal Lobar Degeneration (ALLFTD) research consortium, have reported that a blood test could soon be an important diagnostic tool in detecting the abnormal proteins deposits in the brain that lead to the progressive and debilitating condition of Alzheimer's disease. The study titled, "Diagnostic value of plasma phosphorylated tau181 in Alzheimer's disease and frontotemporal lobar degeneration," was published in today's issue of the journal Nature Medicine.

How cannabis interacts with medications

A new practice guideline published in the journal CMAJ in February 2020 describes five types of drug interactions possible with the use of cannabis. Cannabis is a plant-derived drug containing the psychoactive ingredient delta-9-tetrahydrocannabinol (THC) and non-psychoactive cannabidiol (CBD). These cannabinoids are broken down by the liver enzymes cytochrome P450 C(YP)34A, and CYP2CC9.
