There are two articles in PubMed that link TMAU to seizure activity, anxiety, and learning disabilities. It seems that even though TMAU is not considered to be a serious medical condition, it does seem to wreak havoc with other diseases. In addition to epilepsy, some sufferers who suffer from autoimmune diseases and allergies claim that their odor symptoms seem to trigger their conditions. Much more research is needed in this regard.
Literature reports only two cases affected by trimethylaminuria and epilepsy. We describe a third patient who, from the age of seven, was affected by temporal focal seizures with nocturnal episodes of nausea, vomiting, anxiety and autonomic activation followed by headache...Our patient also showed learning disabilities despite a normal intelligence quotient (IQ), while another described patient had an IQ varying from borderline to mild mental retardation. We discuss the association between trimethylaminuria and epilepsy, and formulate some hypotheses on the relationship between trimethylamine convulsive effect and the anticonvulsive role of levetiracetam.

A 16-year-old left-handed male is presented with a history of seizures associated with a fish-like odour and behavioural disturbances thought to be related to trimethylaminuria...The episodes would start with a fish-like odour, followed by seizures occurring in clusters and behavioural disturbance consisting of agitation, mixed affective symptoms, auditory hallucinations and delusions. A urinary assay of trimethylamine (TMA) was elevated, confirming the diagnosis of trimethylaminuria in this patient. He was treated with a choline-restricted diet with resolution of his symptoms.

A low choline diet isn't the only diet that helps control seizure activity. There is another online article on 3kimt.com about a little boy with epilepsy, not identified as having a TMAU or other odor conditions, who is controlling his seizures with ketogenic diet under the care of Dr. Elain Wirrell, a Pediatric Epileptologist at the Mayo Clinic. Yet Dr. Wirrell associates metabolic conditions as some of the different causes for seizures.
"There are some side effects, it's not for everybody and so there are some different causes for seizures different metabolic conditions which would make it very dangerous to use so we have to exclude those possibilities," said Wirrell.
