Benefits of cognitive-motor intervention in MCI and mild to moderate Alzheimer disease.

OBJECTIVE: To evaluate the efficacy of a cognitive-motor program in patients with early Alzheimer disease (AD) who are treated with a cholinesterase inhibitor (ChEI). METHODS: Patients with mild cognitive impairment (MCI) (12), mild AD (48), and moderate AD (24) (Global Deterioration Scale stages 3, 4, and 5) were randomized to receive psychosocial support plus cognitive-motor intervention (experimental group) or psychosocial support alone (control group). Cognitive-motor intervention (CMI) consisted of a 1-year structured program of 103 sessions of cognitive exercises, plus social and psychomotor activities. The primary efficacy measure was the cognitive subscale of the AD Assessment Scale (ADAS-cog). Secondary efficacy measures were the Mini-Mental State Examination, the Functional Activities Questionnaire, and the Geriatric Depression Scale. Evaluations were conducted at 1, 3, 6, and 12 months by blinded evaluators. RESULTS: Patients in the CMI group maintained cognitive status at month 6, whereas patients in the control group had significantly declined at that time. Cognitive response was higher in the patients with fewer years of formal education. In addition, more patients in the experimental group maintained or improved their affective status at month 12 (experimental group, 75%; control group, 47%; p = 0.017). CONCLUSIONS: A long-term CMI in ChEI-treated early Alzheimer disease patients produced additional mood and cognitive benefits.

Rapid molecular analysis of the haemagglutinin gene of human influenza A H3N2 viruses isolated in spain from 1996 to 2000.

A simple molecular technique was used for the rapid preliminary genetic characterization of human influenza A H3N2 viruses isolated in Spain from 1996 to 2000. Subtyping, based on RT-PCR, was followed by subtype-specific restriction enzyme fragment length polymorphism (RFLP) analyses of an amplified region of the HA1 domain of the H3 haemagglutinin (HA) gene to distinguish variants differentiated by common amino acid substitutions in HA1. The approach was tested using 135 Spanish H3N2 isolates and included nucleotide sequencing and phylogenetic analyses of a region of the HA1 domain of 41 representative isolates. The viruses were distinguished by haemagglutination inhibition (HI) assays into two antigenically discernible groups, the A/Wuhan/359/95-like and A/Sydney/5/97-like viruses. The results of PCR-RFLP analysis allowed a finer classification into five genetic variant subgroups, corresponding to those distinguished by phylogenetic analyses. This rapid, simple and variant-specific procedure could, therefore, be used to rapidly screen clinical specimens prior to more detailed antigenic and genetic analyses.

Interleukin-6 (IL6) and cellular response to facial nerve injury: effects on lymphocyte recruitment, early microglial activation and axonal outgrowth in IL6-deficient mice.

Nerve injury triggers numerous changes in the injured neurons and surrounding non-neuronal cells. Of particular interest are molecular signals that play a role in the overall orchestration of this multifaceted cellular response. Here we investigated the function of interleukin-6 (IL6), a multifunctional neurotrophin and cytokine rapidly expressed in the injured nervous system, using the facial axotomy model in IL6-deficient mice and wild-type controls. Transgenic deletion of IL6 caused a massive decrease in the recruitment of CD3-positive T-lymphocytes and early microglial activation during the first 4 days after injury in the axotomized facial nucleus. This was accompanied by a more moderate reduction in peripheral regeneration at day 4, lymphocyte recruitment (day 14) and enhanced perikaryal sprouting (day 14). Motoneuron cell death, phagocytosis by microglial cells and recruitment of granulocytes and macrophages into injured peripheral nerve were not affected. In summary, IL6 lead to a variety of effects on the cellular response to neural trauma. However, the particularly strong actions on lymphocytes and microglia suggest that this cytokine plays a central role in the initiation of immune surveillance in the injured central nervous system.

[The headache in general neruological practice].

INTRODUCTION: Headache is one of the most frequent causes of consultation in a neurology clinic. We present a descriptive, epidemiological study about such a pathology in a general neurology clinic. We evaluated as the most relevant points the frequency of different types of headaches, the reasons for remission and diagnosis concordance with the remitting doctor, normally the General Practitioner. PATIENTS AND METHODS: The collection of data was carried out by means of structured interviews over a three month period. Apart from the epidemiological data of the subjects, the characteristics of the headache, the medication and its possible overuse, were also collected. A systematic neurological examination of all patients was carried out. RESULTS: 286 patients were included. The frequency of different diagnosis (the most frequent chronic daily headache, 39.2%), the number of patients who abused of analgesics (31.8%) and the diagnosis concordance with the referring doctor (20%) was analyzed among other variables. CONCLUSIONS: The study highlights the high number of patients suffering from daily chronic headache and the fundamental role that the abuse of analgesics plays in this diagnostic entity. The diagnosis concordance is too low. A correct initial diagnosis as a result of a better neurological training in primary care would prevent in greater numbers the abuse of analgesics and would offer a better quality of care.

[Frontal seizures recorded by magnetoencephalography. Case report].

INTRODUCTION: This paper reports the usefulness of magnetoencephalography (MEG) in the anatomical localization of the onset and spread of seizures. CASE REPORT: In a 34-year-old male patient who suffered from drug-resistant complex partial seizures (sometimes generalized) with loss of awareness, magnetic resonance imaging revealed a probable left frontobasal cortical dysplasia. Ictal scalp electroencephalogram showed left frontotemporal theta waves. Electrocorticography (ECoG) registered interictal polyspike discharges and located the seizure onset in the lateral orbital side of the left frontal lobe. Three seizures were registered by MEG, clinically similar to the ones usually experienced by the patient. MEG ictal spike dipole location showed seizure onset coming from the left inferior frontal gyrus (as the ECoG), spreading on to other frontal areas, insula and temporal lobe, all in the left hemisphere. CONCLUSION: MEG may be considered as a useful diagnosis modality in the study of partial seizure physiopathology as well as in its presurgical evaluation.
