“…Along with this, good premorbid functioning and lower cognitive deterioration (especially in executive functions and verbal memory) are observed in comparison with schizophrenia [ 7 ]. It is known that there is a greater incidence of psychosis similar to schizophrenia in patients with temporal lobe epilepsy [ 9 , 12 ]. In the case presented, the EEG performed on the patient showed findings compatible with focal epilepsy in the temporal lobe.…”

“…The psychotic semiology characteristic of temporal lobe epilepsy is olfactory hallucinations. The smell most commonly associated with temporal lobe epilepsy is that of burnt leather [ 12 ]. In our case, the patient reported interictal olfactory and tactile hallucinations.…”

“…In our case, the patient reported interictal olfactory and tactile hallucinations. It is known that somatic delusions can be secondary to olfactory hallucinations in patients with no other history of psychosis [ 12 ]. The combination of antiepileptics and antipsychotics for the treatment of patients with psychosis in epilepsy has become widespread.…”

“…However, there are doubts as to whether the patient actually presented interictal psychosis secondary to her underlying epilepsy. We have the epileptical focus in the temporal lobe [ 18 ], the absence of negative symptoms [ 10 ], olfactory hallucinations [ 12 ], and the duration of the psychotic symptoms [ 19 ]. Also, a higher prevalence of psychosis has been reported in epilepsy [ 6 , 7 ] and epilepsy in psychosis [ 20 ].…”

Psychotic disorders can have a primary or secondary origin. Primary psychosis includes pathologies such as paranoid schizophrenia, acute psychotic episodes, schizoaffective disorder, and other chronic psychiatric disorders. However, in secondary psychosis, there is an organic cause that explains the appearance of psychotic symptoms, such as those secondary to the consumption of psychoactive substances or some neurological or systemic diseases. Psychosis in epilepsy falls under secondary psychosis. It may present as hallucinations and delirium reminiscent of some primary psychoses such as schizophrenia. We present the case of a 57-year-old female suffering from temporal lobe epilepsy who developed psychotic symptoms and whose definitive diagnosis was a challenge given the similarities between some alternative diagnoses, mainly between interictal psychosis of epilepsy and late-onset schizophrenia. We also review the relevant literature. We consider that more studies are required to clarify the relationship between epilepsy and psychosis.

“…Due to its affective, behavioral, and cognitive symptoms, FIAS is often misdiagnosed as a primary psychiatric disorder. Usually, these symptoms are present with others, which are atypical for diagnosing primary psychiatric illness, such as macropsia, micropsia, gustatory and olfactory hallucinations, intense, short-lived delusion, and déjà vu phenomenon [7]. FIAS presents as aura followed by ictal, postictal, and inter-ictal states.…”

Focal impaired awareness seizures (FIAS), previously known as complex partial seizures, refer to focal seizures that start in one hemisphere of the brain and are associated with an impairment in consciousness. FIAS of temporal lobe origin most often present with psychopathology, such as behavioral and affective symptoms. It has a bimodal age distribution peaking at the extremes of life. Geriatric presentations can often be subtle and go unnoticed asides from a few symptoms, such as confusion and memory lapses. Here, we present a unique case of a geriatric patient with FIAS presenting as transient psychosis.
