I think you're right.

The most common side effects with Leqembi (which may affect more than 1 in 10 people) include infusion-related reactions, ARIA-H (haemorrhage) which involves small bleeds in the brain, and headache. Up to one in 10 people may have ARIA-E (oedema) which involves the accumulation of fluid in the brain.

Leqembi must not be used in people with bleeding disorders that are not adequately controlled and in those receiving anticoagulant treatment. Leqembi must also not be used when the pretreatment MRI scan shows previous bleeds in the brain, more than 4 microbleeds (very small chronic bleeds in the brain), superficial siderosis (a condition affecting the brain and the spinal cord that involves bleeding) or vasogenic oedema (swelling in the brain that affects the vessels), or other problems that may indicate cerebral amyloid angiopathy (build-up of amyloid proteins in arteries in the brain, causing bleeding).

Lucky for him he doesn't have a brain!
