Despite a great degree of awareness about epilepsy amongst schoolteachers in India negative and wrong attitudes still exist. Stress on proper first aid measure to a seizing child needs greater emphasis to remove fright and fear amongst the public. Besides adequate management, public education to address existing biases and fear are equally important to improve the quality of life of epileptics.

Japanese encephalitis (JE) is numerically the most important global cause of encephalitis and so far confirmed to have caused major epidemics in India. Most of the reported studies have been in children. This largest study involving only adults, belonging to four epidemics, is being reported from Gorakhpur. The aim of this study is to detail the acute clinical profile (not viral) outcome and to classify the sequelae at discharge. This prospective study involved 1,282 adult patients initially diagnosed as JE admitted during the epidemics of 1978, 1980, 1988, and 1989, on identical clinical presentation and CSF examination. In the meantime, the diagnosis of JE was confirmed by serological and/or virological studies in only a representative number of samples (649 of 1,282 cases). Eighty-three left against medical advice (LAMA) at various stages, so 1,199 of 1,282 were available for the study. Peak incidence of [1,061 of 1,282 (83%)] of clinically suspected cases was from September 15 to November 2. Serum IgM and IgG were positive in high titers in 50.87% (330 of 649) and IgM positive in CSF in 88.75% (109 of 123) of the cases. JE virus could be isolated from CSF and brain tissue in 5 of 5 and 4 of 5 samples, respectively. Altered sensorium (AS) in (96%), convulsions (86%), and headache (85%) were the main symptoms for hospitalization by the third day of the onset. Other neurological features included hyperkinetic movements in 593 of 1,282 (46%)-choreoathetoid in 490 (83%) and bizarre, ill-defined in 103 (17%). The features of brain stem involvement consisted of opsoclonus (20%), gaze palsies (16%), and pupillary changes (48%) with waxing and waning character. Cerebellar signs were distinctly absent. Dystonia and decerebrate rigidity was observed in 43 and 6%, respectively, paralytic features in 17% and seizures in 30%. Many non-neurological features of prognostic importance included abnormal breathing patterns (ABP) (45%), pulmonary edema (PO) (33%), and upper gastrointestinal hemorrhage (UGIH) (16%). Injection dexamethasone was used in 1978 in all 208 cases, including 21 of PO. Patients were later randomized alternately in dexa and non-dexa groups. Forty-six cases of PO from the non-dexa group were transferred to the dexa group as an ultimate life-saving measure. Thus, it was administered in 737 of 1,199 patients including 529 patients from the later epidemics in doses of 4 mg IV every 8 h for 7 days. Of 1,199, 462 did not receive it. There was no significant difference in mortality (p > 0.05) between the dexa (42.47%) and the non-dexa group (42.86%). All PO cases expired; so after the exclusion of the PO cases from dexa group, the difference of 6.14% (42.86 and 36.72) became significant (p < 0.01) (511 of 1,199 (43%) expired, [320 of 511 (63%) died within 3 days of hospitalization]). Out of a total of 1,199 patients treated, 688 (57%) were discharged; 23 of 688 (3%) without any sequelae and 665 of 688 (97%) with neuropsychiatric deficits classified into nine groups. During the four epidemics, the diagnosis of JE w...

Japanese encephalitis, the commonest Arbovirus encephalitis, has been endemic in many parts of Asia, the Pacific Islands, and India; also, there have been many epidemics. Most of the post JE cases have been associated with neurological and neuropsychiatric deficits but have not been properly classified and followed. Practically all the previous studies were in children or young adults. The aim of this study, involving only adult cases, the largest ever being reported, has been to follow the 688/1,199 survivors of JE patients out of 1,282 of acute cases admitted during four epidemics for a period of 14 years after properly classifying the sequelae. This prospective study was conducted in B.R.D. Medical College Gorakhpur (India), involving 665/688 post JE cases with neuropsychiatric deficits from four epidemics of 1978, 1980, 1988 and 1989 which were properly classified in nine groups. While the first epidemic of 1978 was being studied, more disastrous episodes flared up and the patients were subsequently added. Hence, the total duration of this prospective study was from November 1978 to December 2003. There were 14 defaulted initially from 688 followed (23/688 without sequelae and 665/688 with neuropsychiatric deficits), and later 130 were lost from time to time at various stages of follow up. Four out of 23/688 discharged without any deficit had to be readmitted for bizarre movements, assaultative behaviour and euphoria without fever and altered sensorium. All of them improved by symptomatic treatment. Progressive improvement occurred in all the parameters consisting of psychological disturbances, higher cerebral dysfunction, speech disorders (dysphonia, dysarthria, dysphasias, apraxia and agnosia), extra pyramidal, pyramidal features, and hypothalamic disturbances, cranial nerves including pupils and fundi and seizures. Maximum cases improved between 6 months (55%) to 1 year (78%). Only some features improved between 5 to 14 years. Four patients of hemiplegia remained bed ridden. Some non disabling features like dysarthria and corticospinal features without paralysis persisted in 5% (95% improved) and 74% (26% improved) respectively. One patient with bizarre movement and nine with marked tremors could not regain normalcy. A large number of patients of JE are left with several minor or gross residual neuropsychiatric and neurological features after the acute phase. In this series also the discharged patients with neurological deficits who were quite disabled initially and needed constant care by family members and also those who required some help intermittently improved with passage of time and eventually returned to normal life. Some of them were left with non-disabling residual neurological signs even after 14 years. Fourteen of 544 (3%) could not return to their livelihood.
