Possibly. The evidence is mixed, emerging or strongly context-dependent.

MRI studies, including widely cited work by Harvard neuroscientist Sara Lazar, have found measurable differences in cortical thickness and gray matter density in regions like the hippocampus and prefrontal cortex among long-term meditators compared to non-meditators.
Meditation refers to a family of mental practices, commonly mindfulness or focused-attention meditation, where a person sits quietly and directs attention to the breath, a sound or bodily sensations for a set period, often guided by an app or teacher. Sessions can range from a few minutes to an hour or more.
Its cultural momentum comes from a mix of centuries-old Buddhist and contemplative traditions and a modern secular "mindfulness" movement that spread through corporate wellness programs, meditation apps and health journalism. Ongoing scientific interest in brain imaging studies has fed a steady stream of media coverage that keeps meditation framed as scientifically credible.

Relevant mechanisms: attention, breathing pattern, autonomic arousal, interoception, emotional regulation, practice and expectation.
The mechanism has been photographed beautifully. The evidence would still like to see the spreadsheet.
People often start a new intervention when a symptom is unusually bad. Many fluctuating symptoms naturally move back toward their usual level. If a new product was started at the low point, ordinary improvement can look like a treatment effect — the timeline is simply flattering the newest object in the bathroom.
Once someone has invested money, attention and hope, the mind naturally notices confirming evidence. Good day after starting: it worked. Bad day: probably needs another week. No change: maybe the dose is wrong. This is why predefined outcomes and stop rules matter — they protect the experiment from becoming a subscription.
Expectation, attention, previous experience, ritual, sensory cues and other simultaneous behaviour changes can all influence subjective outcomes such as pain, sleep quality, stress, energy and mood. Subjective improvement alone can't tell us which mechanism caused it — that's what a comparison group is for.
Avoid prolonged breath-holding or intense hyperventilation, particularly around water or when fainting would be dangerous.
If you want an honest cue for this behaviour rather than a medical claim, OrcaCalm is built for exactly that job — a placebo, not a treatment.
Does meditation change the brain? Possibly. The evidence is mixed, emerging or strongly context-dependent. There may be a real effect for some people, but it is usually smaller and more specific than the marketing suggests.
Can this replace medical treatment? No. A wellness ritual can complement appropriate care, but it should not replace diagnosis, prescribed treatment or urgent assessment.
