Yo team — a fresh MIT Technology Review piece just dropped about interoception and aging, and this is going to be one of those posts you come back to in five years. Interoception isn't just 'sensing your stomach growling'; it's the brain decoding visceral feedback into actionable information. Our insular cortex constantly compares predicted internal states with actual afferent input. When that loop breaks — which happens as aging neurons degrade and dampen these signals — people start ignoring early warning signs of inflammation, cardiac strain, or metabolic shift until they become acute crises. Salcedo's work at Northeastern on predictive coding shows how the brain can literally learn to misinterpret internal feedback over decades through repeated exposure, creating a self-reinforcing cycle where chronic conditions go untreated because the body's 'dashboard' is broken.
This has massive implications for what we call age-related depression and cognitive decline. Much of it isn't just neurodegeneration; it's emotional dysregulation caused by miscalibrated internal feedback — people feeling constant, unexplained dread or fatigue because their brain can no longer accurately gauge physiological state. The MIT piece highlights that biofeedback training specifically targeting autonomic awareness has already shown reduced depression symptoms in older adults (Utsaha et al.) and could fundamentally change how we approach elderly mental health. Instead of just adding more meds to a tired system, we should be teaching people to decode their own internal signals. This is a complete paradigm shift from treating age as an inevitable decline to treating it as a signal processing problem that can be remediable through neurofeedback training — literally 'reprogramming' the aging brain's sensory input loop rather than just suppressing symptoms with pharmacological Band-Aids.
I keep coming back to the phrase 'the interoception gap.' It captures what I think will become one of the most important discoveries in geriatric medicine this decade. We spend billions on anti-aging drugs and diet hacks that largely mask decline while ignoring the fact that our best diagnostic tool — our own internal feedback system — is being progressively broken by age. If we built technology to help people reconnect with these signals instead of drowning them in wearable data, the whole conversation around aging changes from 'managing a condition' to 'restoring function.' I honestly believe this interoceptive approach will beat any anti-aging compound pipeline on pure long-term outcomes because it addresses the underlying decoding problem. The tech that can bridge the gap between subjective feeling and objective physiological state is worth an entire field of medicine on its own, and we're only at the starting line.
