introduction many conditions can mimic psychiatric symptoms. amongst them, intracranial mass and space occupying lesions have a significant importance. aggression and hallucination are seen in association with a basal frontal lesion, and may mimic psychotic syndromes. case presentation a 37-year-old man with no previous mental illness presented with a month history of headache, blurred vision, ...

This study examined the effect of cosmetic therapy on frontal lobe activation as revealed by topographic near-infrared spectroscopy (NIRS). We evaluated emotional responses to a photograph of a face with/without makeup by 22 healthy female volunteers (mean age, 52 ± 10.5 years). The results of the first-round analysis showed a significant increase of oxy-Hb in the frontal lobe area when the sub...

The paroxysmal motor events during sleep are certainly common.The systematic use of nocturnal video-polysomnography has largely improved the diagnostic yield in patients with clusters of nocturnal motor events. Two broad nosological categories have been identified: parasomnias (sleep terror and sleep-walking), which are thought to represent disorders of arousal during sleep,and the epileptic se...

About one-quarter of patients with refractory focal epilepsies have frontal lobe epilepsy (FLE). The typical seizure semiology for FLE includes unilateral clonic, tonic asymmetric or hypermotor seizures. Interictal electroencephalograms (EEG) usually reveal interictal epileptiform discharges and rhythmical midline theta, which has localizing value. The usefulness of ictal EEG recordings is limi...

Abstract The frontal lobes represent a large area, consuming approximately one-third of the cortical surface of the brain. This area is involved directly and indirectly across a wide spectrum of human thought, behavior and emotions. The irony of the frontal lobes may best be described as the area of the brain we know the most about but understand the least. For example, frontal lobe functioning...

Tuberculomas are usually infratentorial in children, and supratentorial lesions predominate in adults. We present a 4-year-old girl with multiple seizures, papilloedema and brisk reflexes. On investigation, she was found to have a large left parafalcine tuberculoma. She was treated with antitubercular treatment (ATT) and steroids. The child improved, seizures stopped and the papilloedema gradua...

Stroop's test and the Verbal Fluency test are commonly argued to be measures of the integrity of the prefrontal cortex. This assumption has only to some degree been confirmed by lesion studies. In the present study, Positron Emission Tomography (PET) with H(2)(15)O was used to further validate Stroop's test and the Verbal Fluency as measures of frontal lobe function; both tests were implemented...

Free recall, use of organizational strategies, and interference effects were assessed in patients with frontal lobe lesions and control subjects. In three experiments, patients with frontal lobe lesions exhibited impaired free recall and reduced use of organizational strategies in tests of memory. Reduced use of strategies was observed on tests of recall of unrelated items, as measured by subje...
