what it claims

Chronic anxiety can lead to structural hyperactivity in certain brain regions, such as the amygdala, which keeps the body in an inappropriate state of alertness.

The creator here describes the mechanism of the 'fight-or-flight' response and its potential dysregulation. Scientific literature, notably neuroscience meta-analyses (e.g., Etkin & Wager, American Journal of Psychiatry), does indeed confirm amygdala hyperreactivity in individuals suffering from anxiety disorders. It is also established by brain imaging studies (MRI) that chronic stress can induce changes in synaptic plasticity in these areas, although the term 'structural change' is a popularized simplification of complex remodeling phenomena. The assertion that these areas become 'hyperactive' is supported by numerous observational studies. However, the creator wisely nuances this by specifying that the exact mechanisms remain partly misunderstood, which is entirely accurate regarding current research. There is no notable exaggeration here; the discourse remains faithful to current neurobiological models of anxiety.

What the graded evidence says

Evidence: B

Effect: mindfulness meditation vs active control on anxiety, depression, pain, and attention (meta-analysis of RCTs) — anxiety effect size 0.38 (95% CI 0.12-0.64) at 8 weeks; depression 0.30 (0.00-0.59); pain 0.33 (0.03-0.62); low/insufficient evidence for effects on attention
Measured on: diverse adult clinical populations

Effects on stress and mood are small-to-moderate; the evidence that meditation improves attention or concentration specifically is weak. It was not better than other active treatments like exercise or therapy.
