Bert Tuk
Bert Tuk, PhD
  • Scientific advisor to SEVBI.
  • With an academic background on the clinical pharmacology of CNS drugs, and subsequent serving on a multitude of client projects on neurological diseases, Bert developed the groundbreaking new insight that it is actually the body-own inhibitory system that causes the inhibition of function in patients with neurological and neuromuscular diseases. He further discovered the prior treatment success in ALS patients of a safe and effective treatment regimen with known drugs that restore the function of the inhibitory system, aiming at the reversal of symptoms in ALS. The observed reversal of symptoms is seen as a challenge to the current scientific dogmas in neurology that assume that the paralysed muscles result from neuronal cell death and therefore cannot be reversed. SEVBI was created around the observation that available off-label treatments with a favourable benefit and risk ratio were not used in clinical practice, not even in ALS. Bert is facilitating the enablement of fast and affordable access to the treatments with high moral and patient values.
