Welcome to our Neurology Flashcards! Understanding is paramount, but unfortunately, one aspect of academic success does rely on simple memorization and repetition. We have taken the most commonly seen rote memory topics and “buzzwords” from neurology board and RITE* exams and made easy-to-use flashcards. These work on desktop, tablet, and mobile devices.
Dermatomyositis antibody associated with highest cancer risk
Anti-TIFγ
Both polymyositis and dermatomyositis (DM) have cancer risk, but risk is higher with DM, especially when anti-TIFγ is present (5-fold increase, usually breast).

Mechanism of action
Malignant hyperthermia treatment
Prevents release of calcium from sarcoplasmic reticiculum, perhaps by binding to RYR1 receptor.
