Level 5 - mechanism / opinion, no new human data
Theoretical hypothesis and narrative review without original data
PubMed 21459521 · doi:10.1016/j.mehy.2011.01.020
What was done
A PubMed literature search was conducted using the terms antidepressant tachyphylaxis, treatment-resistant depression, chronic depression, and antidepressant tolerance to synthesize a conceptual framework regarding long-term antidepressant use.
What was found
The abstract reports no quantitative data or statistics. It describes clinical patterns where patients with treatment-resistant depression initially responded well to antidepressants after prolonged high-dose treatment, and introduces the term "tardive dysphoria" with a hypothesized mechanism related to dendritic arborization.
Why it matters
It proposes a theoretical construct suggesting that chronic antidepressant exposure might itself induce or sustain treatment-resistant depression in susceptible individuals.
Limits
This is a speculative narrative review and hypothesis paper containing no original empirical or quantitative clinical trial data. No sample sizes or included study counts are reported in the abstract.
