A small new Brazilian study published in the international Journal of Alzheimer's Disease investigated the effects of microdoses of cannabis extract on patients with mild Alzheimer's disease. The results found positive effects, without the associated “high” of cannabis.

The logic of microdoses
The study, led by professor Francisney Nascimento and colleagues at the Federal University of Latin American Integration (UNILA), recruited 24 elderly patients (60-80 years) diagnosed with mild Alzheimer's. It evaluated the effects of daily use of an oil prepared from Cannabis extract containing THC and CBD in similar proportions and extremely low concentrations (0.3 mg of each cannabinoid). These sub-psychoactive doses do not cause the “high” associated with recreational use of the plant.

In time to celebrate the superstar’s birthday, HarperCollins India is delighted to bring out the ‘Bollywood book of the year’ by award-winning writer Mohar Basu – Salman Khan: The Sultan of Bollywood. This book is not just a biography, but a love letter, a fan’s tribute and a deep dive into the incredible phenomenon called Salman Khan – through his iconic roles, memorable one-liners, unforgettable songs, rare photos and fan anecdotes, bringing to life an icon’s larger-than-life journey and his stardom that has only grown stronger with time. The book will be out on 20th December 2025.

Talking about the book, Mohar Basu says, “I have struggled to enjoy most of the films I’ve watched this year. The big-screen experience simply doesn’t feel the same anymore. When I ask myself what’s missing, the answer is clear – it is the uninhibited joy of watching a movie star on a 70mm screen. And there is no one who embodies this feeling like Salman Khan. The electric rush of a first-day-first-show at a single-screen theatre, the crowd comes alive the moment a superstar like Salman Khan makes his rousing entry. Salman Khan: The Sultan of Bollywood is my tribute to the phenomenon of Salman Khan. The book captures the euphoria of watching him on screen, why he has been a ritual for us for the past three decades and what makes him the greatest ‘mass’ hero of our time. As he turns 60, this book celebrates the old-school magic of movies and why no one commands the big screen quite like Salman Khan.”
