Overview
- After appearing on a January 3 podcast with the device clipped to his temple, Goyal said the prototype tracks brain oxygenation as an indirect sign of blood flow and is not for sale.
- Neurologists and radiologists from AIIMS, Apollo, Wockhardt and KIMS say there are no clinical trials, peer‑reviewed studies or independent validation proving accuracy.
- Experts note that near‑infrared spectroscopy estimates oxygenation rather than measuring deep cerebral perfusion and is vulnerable to motion artifacts and superficial blood signals.
- Doctors emphasize that validated tools like Transcranial Doppler, CT/MRI perfusion and angiography remain the standard for assessing cerebral circulation in clinical settings.
- Several clinicians criticized the ‘Gravity Ageing Hypothesis’ behind the project and advised treating the wearable as an experimental or wellness gadget with no role for healthy users.
