We report on the autoradiographic distribution of 5-HT1B, 5-HT1D and 5-HT1F receptor subtypes in human brain, focusing on the brainstem and cervical spinal cord. We have used [3H]sumatriptan as a radioligand in the presence of suitable concentrations of 5-CT (5-carboxamidotryptamine) to define 5-HT1F receptors, and ketanserin, to discriminate between 5-HT1B(More)
Using [3H]sumatriptan as a radioligand, 5-hydroxytryptamine (5-HT)1B receptors were examined in posterior striatum and midbrain post-mortem tissue sections of 12 patients who had died from representative degenerative movement disorders as compared to nine controls. In the control human basal ganglia, the highest densities of [3H]sumatriptan binding were(More)
We describe an exceptional spinocerebellar ataxia type 2 (SCA2) phenotype combining cerebellar ataxia, levodopa-responsive parkinsonism, and motor neuron symptoms. We conclude that motor neuron symptoms and signs may be a striking manifestation in SCA2, masking pre-existing cerebellar and extrapyramidal semeiology.
Migraine is a disabling neurological disease that affects 14.7 % of Europeans. Studies evaluating the economic impact of migraine are complex to conduct adequately and with time become outdated as healthcare systems evolve. This study sought to quantify and compare direct medical costs of chronic migraine (CM) and episodic migraine (EM) in five European(More)
In the present work the anatomical distribution of alpha 2-adrenoceptors in the human central nervous system was studied in detail by quantitative autoradiography using the selective alpha 2 agonist [3H]bromoxidine ([3H]UK-14304) as a ligand. Only postmortem tissues from subjects free of neurological disorders were used in this study. Very high or high(More)
Mutations in the leucine-rich repat kinase 2 (LRRK2) gene have been shown to cause both autosomal dominant and sporadic Parkinson's disease (PD). The common G2019S mutation shows wide geographical distribution while R1441G has been only reported in Northern Spain. The overall frequency of these mutations remains to be established. To determine the(More)
Migraine is a genetically complex disorder in which sexual hormones influence the phenotype. ESR1 G594A polymorphism has been associated with migraine in Australians. We performed a case-control study with G594A and G325C polymorphisms to determine whether ESR1 is associated with migraine in our population. An association between G594A and migraine could(More)
We studied the autoradiographic densities of all pharmacologically characterised muscarinic receptors (MR) in frontal, temporal, and visual cortex, hippocampal formation, and striatum in autopsied brains from 19 histopathologically verified patients of Alzheimer's disease (AD) and in matched controls. Almost all (16 of 19) of the AD cases were severe. In AD(More)
To examine directly in the brain the status of alpha 2-adrenoceptors in major depression, the specific binding of the agonist [3H]UK 14304 was measured by quantitative receptor autoradiography in the hippocampus and frontal cortex of suicide victims (n = 17) with a retrospective diagnosis of depression (n = 7) or other psychiatric disorders (n = 10) as well(More)
The autoradiographic pattern of cholinergic muscarinic receptors in the brain of two newborn infants with Down syndrome (DS) (stillbirths, 31 and 39 gestational weeks), were compared with that of age-matched control fetuses. Densities and distribution patterns of muscarinic receptors in the forebrain were similar in both groups. However, a marked receptor(More)
