This report concerns three patients with cluster headache-like headaches associated with intracranial pathologic findings. The question whether the occurrence of cluster headache-like headaches may be a symptomatic feature is still not solved. In two of the three presented cases the cluster headache-like headaches disappeared when the intracranial abnormalities were treated.
The prevalence of clinical dementia was assessed in three age groups of patients with Down syndrome in the county of Aarhus, Denmark: Group 1: 14-16 years (n = 13), group 2: 23-29 years (n = 34), group 3: 50-60 years (n = 25). Seventy-two (85%) of 85 patients participated. Caregivers were interviewed and a neurological examination was performed. An EEG was recorded in 50 patients. Definite clinical dementia was defined as an acquired and progressive decline in 4 or more out of 17 items that are considered to indicate dementia in Down syndrome. Possible dementia was considered when 1-3 items were affected. Six (24%) in group 3 had definite clinical dementia. A further 6 patients in group 3 and 2 (6%) in group 2 had possible dementia. This is the first population-based study with a clinical assessment of the prevalence of dementia in Down syndrome.
In spastic patients the alpha-adrenergic blocking drug thymoxamine (Opilon Forte) was found capable of depressing most propioceptive reflex parameters within 1 min after intravenous administration. The action seems to be of CNS origin, probably exerted as a depression of spindle stretch sensitivity through descending alpha-adrenergic bulbospinal pathways, but an additional action on the mechanism of presynaptic inhibition is likely. With oral administration, the drug is also capable of depressing distressing clonus, and it is concluded that it deserves further testing as a spasmolytic.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
