The number of people complaining about different symptoms that may be associated with exposure to electromagnetic fields (EMF) has increased rapidly during past years. Students use both mobile phones and video display terminals frequently. The purpose of this study was to investigate the association of mobile phone use and EMF health hazards. Basic demographic data and self-reported symptoms were sought using a questionnaire administered to all apparently healthy students at Rafsanjan University of Medical Sciences (RUMS) and Vali-e-Asr University (VAU). Questions about some major confounding factors such as age, gender, amount of video display terminal work were also included. Exact Fischer Test was used for data analysis. Among self-reported symptoms, headache (53.5%), fatigue (35.6%), difficulties in concentration (32.5%), vertigo/dizziness (30.4%), attention disorders (28.8%), nervousness (28.1%), palpitation (14.7%), low back pain (14.3%), myalgia (12.4%), and tinnitus (9.9%) were the main self-reported symptoms. No significant differences in the prevalence of these symptoms were found between CRT users and those who did not use CRTs. A significant association was found between cordless phone use and difficulties in concentration (P < .05) or attention disorders (P < .05). However, after correction of the gender role, these differences were not significant. No association was found between mobile phone use and the above-mentioned symptoms. No significantly higher prevalence of self-reported symptoms was found in individuals who had used mobile phones, video display terminals or cordless phones more frequently than others. Mass-media's lack of interest in the possible hazards of exposure to EMF in developing countries can explain the difference observed between the results of this study and those of other researchers in some developed countries who have shown an association between EMF exposure and the prevalence of self-reported subjective symptoms. This finding can confirm the results obtained in provocative studies which indicated the role of psychological factors in electromagnetic hypersensitivity. More research is needed to clarify whether daily environmental EMF may cause health problems.

Alexander disease is a neurological condition associated with prominent white matter deterioration. Its rarity and relatively rapid disease course have provided limited understanding into the cognitive effects of the illness. We report the serial neuropsychological findings of a 21-year-old with normal development and no medical history until age 9, when he experienced refractory sinusitis, stabbing headaches with vertigo, disorientation, and decline in academic and social settings. An MRI scan of the brain found acute demyelinating encephalomyelitis, with a preponderance of white matter degeneration in the bilateral frontal lobes. Interval MRIs showed continued degeneration. Confirmation of Alexander disease was made at age 20 through genetic testing. Four evaluations completed from ages 15 to 21 showed impairment across all cognitive domains. Cognitive deficits were most prominent in new learning and recent memory, executive functions, and fine motor dexterity, and less apparent in information processing and visual scanning speed. These results present evidence for a particular cognitive pattern in individuals with juvenile-onset Alexander disease. Despite extensive white matter degeneration in the frontal lobes, certain tasks associated with frontal lobe integrity were relatively preserved. Further research into the neuropsychological presentation of the subtypes of Alexander disease can enhance diagnostic clarity and treatment planning.

A study was based on the survey of 419 neurologists and 1189 their patients with different forms of cerebrovascular diseases using a specially developed questionnaire. In most cases, vasobral was used as a monotherapy or in a complex treatment. Twenty-two percent of physicians reported that vasobral was the most effective compared to other drugs. The good tolerability of treatment (18%) and the broad spectrum of indications and clinical effects (17%) were reported as well. The large percentage (75%) of patients indicated the positive effect of vasobral on memory, reasoning, vertigo etc The maximal effect was identified in the treatment of mild cognitive impairment caused by chronic brain ischemia and vertebrobasilar insufficiency. Vasobral is recommended for a use in a complex therapy in patients with more severe brain lesions and cognitive deficit.
