Human tissue evidence still requires attention to the clinical exposures behind the specimen.
What the paper found
A temporal-lobe epilepsy study examined GABA-related measures in patients with psychiatric symptoms. Most patients had received several antiseizure medicines, including drugs with GABA-related actions such as clobazam, clonazepam or diazepam.
What the evidence cannot establish
Severe disease, multiple treatments and surgical selection complicate separation of medication effects from disease biology. A small tissue sample cannot represent every person with epilepsy or anxiety.
Implications for forensic review
Read the treatment history before assigning a receptor or neurotransmitter difference to a single cause. The study can support biological hypotheses but cannot establish that one benzodiazepine caused a psychiatric symptom, that the disease alone produced the difference, or that a particular dose would normalize it.
