Herbs · Ashwagandha

Ashwagandha ingestion is temporally associated with acute neurotoxicity including prolonged sleep, abnormal sleep behaviors, acute confusion, and retrograde amnesia.

A 40-year-old man developed prolonged sleep, abnormal sleep behaviors, acute confusion, and retrograde amnesia after ingesting ashwagandha. Comprehensive evaluation excluded other causes, and symptoms resolved completely upon discontinuation and supportive care.

Ashwagandha ingestion is temporally associated with acute neurotoxicity including prolonged sleep, abnormal sleep behaviors, acute confusion, and retrograde amnesia. The current body of evidence comprises 1 study. EvidenceHub rates the overall confidence at 32/100 (low).

The Claim

Ashwagandha ingestion is temporally associated with acute neurotoxicity including prolonged sleep, abnormal sleep behaviors, acute confusion, and retrograde amnesia.

This conclusion is most relevant to: A 40-year-old man.

What the Research Shows

The conclusion draws on 1 linked study. Highlights from the cited literature:

  • Parasomnia, Acute Confusion, and Transient Amnesia Temporally Associated With Ashwagandha Ingestion. (Cureus, 2025) —

How It Works

The proposed biological pathway:

  • Withanolides in ashwagandha modulate GABAergic activity
  • Interindividual variability in drug metabolism affects susceptibility
  • GABAergic modulation leads to neuropsychiatric effects
  • Result: acute neurotoxicity with confusion, amnesia, and sleep disturbances

Who Might Benefit

Evidence fit by population:

  • A 40-year-old man

Limitations & Caveats

Important context when interpreting this evidence:

  • Single case report, not generalizable to broader population
  • No control group or blinding; causality cannot be definitively established

Frequently Asked Questions

What is ashwagandha?

Ashwagandha (Withania somnifera) is an adaptogenic herbal supplement commonly used for stress reduction and wellness.

What adverse effects were reported in this case?

The patient experienced prolonged sleep, abnormal sleep behaviors, acute confusion, and retrograde amnesia.

Did the symptoms resolve?

Yes, complete symptom resolution occurred after discontinuing ashwagandha and providing supportive management.

What is the proposed mechanism for these effects?

The effects may be due to GABAergic modulation by withanolides, with individual differences in metabolism increasing susceptibility.
