  • Vision Restoration Therapy: a reply
    Lies Bouwmeester

    Dear Editor,

    We write in response to the eLetter by Philip L Clatworthy on our systematic review ‘the effect of visual training for patients with visual field defects due to brain damage’ (1).

    The focus of the study was to contribute to the development of appropriate methods for patients with visual field defects. During the literature search we were amazed that there were only few methodological sound tr...

  • Ethics in deep brain stimulation for alcohol dependence
    Emily C Bell

    Dear Editor

    JJ Kuhn and colleagues (2007) report a remarkable change in abuse and dependence behavior using DBS neurosurgery.(1)

    First, before DBS could become a potential therapeutic option in alcohol dependence, several factors should likely be considered as suggested by the authors. A key consideration in extending DBS to alcohol dependent patients would be the fact that many patients seeking treatmen...

  • chorea induced by pontine lesions.
    Harald De Cauwer

    Dear Editor

    We read with interest ‘Hydrocephalus induced chorea’ by Voermans, Schutte, and Bloem (J Neurol Neurosurg Psychiatry 2007; 78: 1284-1285). They discuss the causal relation between white matter lesions in the basal ganglia and chorea. Pontine lesions however are not mentioned. We found in this journal two previous cases of pontine myelinolysis and extrapontine myelinolysis and extrapiramidal symptoms.1...

  • Retrograde cerebral venous air embolism, a grossly underestimated differential diagnosis.
    Christoph J. Schlimp

    Dear Editor

    We read with great interest the submitted neurological picture of Jeon et Kang.(1) Together with two recent case reports in the neuroscience field,(2,3) it might have failed to spot the grossly underestimated differential diagnosis of retrograde cerebral venous air embolism secondary to central venous access.(4) In contrast to the well studied and reported paradoxical cerebral arterial air embolism in...

  • The Corpus Callosum: evolving duties throughout life
    Jonathan T. Kleinman

    Those who do not stop asking silly questions become scientists.

    Dear Editor,

    To date, most studies investigating functional correlates of corpus callosum morphometry have been based on small samples. Jokinen and colleagues link mental slowing on specific tasks to atrophy in distinct subdivisions of the corpus callosum (CC) in a large sample of older adults with white matter lesions(1). The authors hypoth...

  • More efforts is needed
    Rizaldy Pinzon

    Dear Editor,

    Individual with an ischemic or hemorrhagic stroke accounts for about 5 % of all stroke if younger than 45 years of age. The cause of stroke in young differs dramatically compared to the elderly. The most common causes for stroke in young are: cardiac disease, hematological, and dissection.

    The stroke risk factors more complex. Lee, et.al, (2002) found the 4 most common risk factors were hyp...

  • Hyperhomocysteinemia a possible risk factor for ischemic strokes
    Sanjith Aaron

    Dear Editor

    I read with interest the article by Lipska et al1 evaluating the risk factors for young stroke in South India . This study could have also looked at the possible association of an elevated serum Homocysteine level as a risk factor for stroke .There are data supporting even mild to moderate hyperhomocysteinemia as a possible risk factor for ischemic strokes 2, 3

    Elevated levels of Homocys...

  • Lateralities of motor command and unilateral motor symptoms in complicated migraine.
    iraj derakhshan

    08.12.07

    Dear Editor

    I read the article of Young and colleagues 1 on migraine with unilateral motor symptoms (MUMS) with great interest. As the article contains laterality-indexed aspects (see below) it begs further clinical information from the authors. Thus, “of the 24 patients with MUMS, 21 (88 %) reported unilateral headaches. The weakness was always ipsilateral to the headache in 13 (62 %) patients...

  • Vitamin D may suppress infections which lead to development of Multiple Sclerosis
    Steven R Brenner

    Dear Editor,

    I read the article with reference to the inverse relationship between multiple sclerosis clinical activity and deficiency of vitamin D by Soilu-Hannienen (1) with interest, and was considering what mechanism could be in play to cause such a relationship.

    25-hydroxylated metabolites of vitamin D act as intracellular regulators of the synthesis and action of defensin (2) molecules against b...

  • Catecholaminergic grafts and revascularization
    Hernando Rafael

    Dear Editor,

    I wish to comment on the surgical experience by Mínguez- Castellanos and colleagues (1 ) about the carotid body(CB) autotransplantation in each putamen and head of the caudate nucleus in 13 patients with advanced Parkinson´s disease (PD ). CB cell aggregates used for transplantation were placed stereotactically throught a burr hole made in the frontal region, close to the coronal suture. The pie...
