Matching patterns of sales data for lottery games in one American county for a year against daily temperature has revealed that sales for scratch tickets (many options to select) fell by nearly $600 with every 1° Fahrenheit increase in temperature. On the other hand, sales for lotto tickets, which require fewer decisions, were not affected.
It’s estimated that 43%-70% of those with multiple sclerosis suffer from some level of cognitive impairment (yes, a very broad range! perhaps the finding of this study offers one clue why). Most commonly, this is seen in slower processing speed, impaired memory, impaired executive function, and poorer visuospatial processing. There are a number of factors that have been implicated in why some people suffer from cognitive impairment and others don’t, such as age of onset and male gender. As with dementia, depression also may be a factor, while cognitive reserve appears protective.
