Abstract
BACKGROUND Neuroprotective strategies are becoming relevant to slow down dopaminergic cell death and inflammatory processes related to the progressive neurodegeneration in Parkinson's disease (PD). Interestingly, among others, physical activity (PA) or anti-oxidant agents (such as N-acetyl-L-cysteine, NAC) are common therapeutic strategies. Therefore, this study aims to analyze if there is a synergistic effect of physical activity along with NAC treatment on dopaminergic degeneration and neuroinflammatory response in a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced Parkinsonism model after subchronic intoxication. METHODS To ascertain this possibility, 48 8-week-old male mice (C57BL/6 strain) were used. Twenty four of them were placed individually in cages where voluntary physical activity was automatically monitored during 30 days and were divided into groups: (i) control; (ii) NAC; (iii) MPTP, and (iv) MPTP+NAC. The other 24 mice were divided into the same four groups but without physical activity. RESULTS The data collected during the treatment period showed that there was an overall increase in the total running distance in all groups under physical activity, including Parkinsonian animals. However, the monitoring data per day showed that the activity routine by MPTP and MPTP+NAC groups was disrupted by alterations in the circardian rhythm because of MPTP intoxication. Results from post-mortem studies in the substantia nigra pars compacta (SNpc) showed significant decrease in the number of TH+ cells in all MPTP groups. Moreover, TH+ expression in the striatum was significantly decreased in all MPTP groups. Thus, PA + NAC treatment do not protect dopaminergic neurons against a subchronic intoxication of MPTP. Regarding glial response, the results obtained from microglial analysis do not show significant increase in the number of Iba-1+ cell in MPTP+NAC and MPTP+PA + NAC. In the striatum, a significant decrease is observed only in the MPTP+NAC group compared with that of the MPTP group. The microglial results are reinforced by those obtained from the analysis of astroglial response, in which a decrease in the expression of GFAP+ cells are observed in MPTP+NAC and MPTP+PA + NAC compared with MPTP groups both in the SNpc and in the striatum. Finally, from the study of the astroglial response by the co-localization of GFAP/S100b, we described some expression patterns observed based on the severity of the damage produced by the MPTP intoxication in the different treated groups. CONCLUSIONS These results suggest that the combination of physical activity with an anti-oxidant agent does not have a synergistic neuroprotective effect in the nigrostriatal pathway. Our results show a potential positive effect, only due to NAC treatment, on the neuroinflammatory response after subchronic MPTP intoxication. Thus, physical activity is not essential, under these conditions. However, we believe that physical activity, used for therapeutic purposes, has a beneficial long-term effect. In this line, these results open the door to design longer studies to demonstrate its promising effect as neuroprotective strategy.

Abstract
Autoimmune encephalitis is an important contributor to rapidly progressive cognitive and behavioral decline. The purpose of this work was to evaluate the effects of cognitive rehabilitation in a patient with autoimmune encephalitis. We also wanted to evaluate the effectiveness of rehabilitative treatment by monitoring the cognitive and metacognitive outcomes over a time interval. We reported a case of 22 year-old female patient with autoimmune encephalitis, cognitive behavioral impairments, and severe reduction in metarepresentational capacity. We performed an assessment of personality, neuropsychological, and meta-cognitive functions at the beginning of the rehabilitative training. The last evaluation was performed six months after the discharge from the rehabilitation unit. We applied a combination of remediation, psycho-educational treatment, and psychotherapy to improve the knowledge and the empathy of the patient, to promote the selfcontrol strategies, and to prompt better behavioral management. Our findings revealed an improvement in the performance of the individual tests after rehabilitative training.

Abstract
We investigated seizure, intelligence quotient (IQ), and neurological outcomes including the process of motor function recovery after functional right hemispherectomy in 3 children with Rasmussen's encephalitis (RE). Before the procedure, they were unable to walk, nor sit without support due to progressive worsening of left hemiplegia and relentless epilepsia partialis continua (EPC) of the left extremities, which were refractory to antiepileptic drug and immunological treatment. After functional right hemispherectomy, EPC completely disappeared, although complete left hemiplegia was sustained. However, they recovered up to being able to walk independently with assistance devices, and to have an ordinary life with family support within 1.5 to 5 months through rehabilitation. At the same time, the interictal EEG improved on the unaffected side of hemisphere, exhibiting a posterior alpha rhythm. Their IQ also improved, and they were able to attend school. Early functional hemispherectomy should be considered before patients with RE are left in a serious condition due to progressive worsening of hemiplegia and seizures refractory to the available treatment.

Abstract
Memory and executive problems following encephalitis are common yet there are few published papers on the successful rehabilitation of such patients. We recently demonstrated (Wilson, Emslie, Quirk, & Evans, 2001; Wilson, Emslie, Quirk, Evans, & Watson, 2005) that a paging system could reduce the everyday memory and planning problems for people with non-progressive brain injury. Among the 143 patients who participated in the 2001 study were four people who had survived encephalitis. Their results are reported here. During a 2-week baseline, the successful task achievement of our four clients ranged from 2-81%. They then received a pager for 7 weeks and task achievement was documented in weeks 6 and 7. All were significantly more successful with the pager than they had been at baseline with success rates ranging from 45-96%. Five weeks after returning their pagers they were monitored once more. One of the encephalitic patients failed to achieve any of his target tasks, returning to baseline level, the other three dropped back a little but were still significantly more successful than at baseline. It is concluded that the paging system can reduce everyday memory and planning problems of patients with encephalitis.

Abstract
In the summer of 2000, an outbreak of WNF affected Israel. Thirty-two elderly patients were admitted to Meir Hospital. WNF encephalitis may result in residual functional damage. However, little information is available regarding the rehabilitation of these patients. Five elderly subjects with residual functional damage were referred to geriatric rehabilitation. Patients were treated with the routine program for neurological rehabilitation after stroke, including daily physiotherapy and occupational therapy. All five were over 77 years and independent before admission. The mean FIM score on admission was 71 (S.D. = +/-8.5) and increased to 102 (S.D. = +/-14) on discharge. MMSE on admission was 60% (S.D. = +/-7.5%), and increased to over 90% on discharge in all of the patients. Clock Completion Test was normal in four on admission, and improved to normal in the fifth patient on discharge. WNF encephalitis may present with functional and intellectual impairment in the elderly. Routine geriatric neurological rehabilitation may benefit those with prolonged functional decline.

Abstract
In 28 patients of a neurological rehabilitation unit of a hospital the use of enteral nutrition via percutaneous endoscopic gastrostomy (PEG) tubes was reviewed. During a total observation period of 5,172 days no life-threatening complications occurred. Minor complications were observed in 12 patients (43%) in the first 2 weeks after the insertion and in 5 patients (18%) afterwards. The nutritional status stabilized in all subjects. Transient PEG feeding was performed in 11 patients (39%) with a mean duration of 150 days. We conclude that hesitation in the application of PEG feeding in neurological rehabilitation should be abandoned. The timing and monitoring of PEG feeding in patients undergoing neurological rehabilitation for acute remitting neurological disorders is discussed.

Abstract
Three severely aphasic hearing patients with no prior knowledge of sign language were able to acquire competency in aspects of American Sign Language (ASL) lexicon and finger spelling, in contrast to a near complete inability to speak the English counterparts of these visuo-gestural signs. Two patients with damage in left postero-lateral temporal and inferior parietal cortices mastered production and comprehension of single signs and short meaningful sign sequences, but the one patient with damage to virtually all left temporal cortices was less accurate in single sign processing and was unable to produce sequences of signs at all. These findings suggest that conceptual knowledge is represented independently of the auditory-vocal records for the corresponding lexical entries, and that left anterior temporal cortices outside of traditional "language areas" are part of the neural network which supports the linkage between conceptual knowledge and linguistic signs, especially as they are used in the sequenced activations required for production or comprehension of meaningful sentences.

Abstract
Patients with Herpes simplex encephalitis often are considered to be poor rehabilitation candidates because of their multiple deficits and grave prognosis. This report presents case reports on three patients with biopsy-proven Herpes simplex encephalitis, all of whom were treated with acyclovir in acute care and then admitted to an inpatient rehabilitation program. All had multiple brain lesions with minimal motor findings but cognitive and communication deficits. One patient, two weeks after admission, slipped into a coma and was transferred to an acute care hospital where he subsequently expired. The other two made useful functional gains and were discharged home in two weeks and 10 weeks, suggesting that a trial of rehabilitation may be warranted after Herpes simplex encephalitis.

Abstract
This paper presents a treatment program for the development of personal hygiene behavior in a patient who was 5 years post herpes simplex encephalitis. The patient has severe memory and organizational problems, but is of average overall intelligence. The program consists in part of chaining a series of nine discrete activities by using linking phrases. The program allowed the patient to structure his behavior and wash in a well-organized nonrepetitive way. Results are discussed in the light of previous failures to affect behavior using apparently similar methods.

Abstract
Foi investigado o possível comprometimento psíquico de pacientes com seqüelas da encefalite por arbovirus, do litoral sul do Estado de São Paulo (Brasil), com a finalidade de definir o papel do psicólogo, em um programa de reabilitação física e psicossocial. A presença das seqüelas era encarada de forma depreciativa e observou-se que essa percepção comprometeu fundamentalmente a identidade do paciente como ser humano, trazendo uma série de respostas emocionais desadaptadas e impossibibilitando a convivência satisfatória consigo e com o próximo. Os resultados analisados, em seu aspecto psicossociológico, revelaram que as dificuldades psíquicas observadas eram originárias da maneira como a deficiência física é encarada no meio social.
