Biogen research chief says 'misinformation' is cause for controversy surrounding newly approved Alzheimer's drug
Dr Alfred Sandrock, head of research and development at Biogen, published a letter combatting 'misinformation' surrounding its drug, Aduhelm
He says that debate over whether the drug works is normal after FDA accelerated approval
Cleveland Clinic and Mount Sinai both said they will not administer the controversial drug to patients
Aduhelm received FDA approval last month despite little evidence that it worked in clinical trials
Drug will cost an individual $56,000 for a year of treatment, and could cost Medicare as much as $29 billion a year
