Women may keep verbal memory skills longer than men in the early stages of Alzheimer’s

first_imgPinterest LinkedIn Women performed better than men on the tests of both immediate recall and delayed recall among those showing evidence of minimal to moderate amounts of hippocampal shrinkage. At the high level of hippocampal shrinkage, there was no difference in the scores of men and women. At the score that indicates the start of verbal memory impairment, or 37 on a scale of zero to 75 for immediate recall, women showed greater evidence of hippocampal shrinkage (ratio of hippocampal volume to total brain volume multiplied by 103 was 5 compared to 6 for men).Mary Sano, PhD, of Icahn School of Medicine at Mount Sinai in New York, NY, and a member of the American Academy of Neurology, said in a corresponding editorial, “At a public policy level, the potential health care cost for under-detection or delayed diagnosis of women with Alzheimer’s disease or its early stages is staggering and should motivate funding in this area.”“If these results are confirmed, then we may need to adjust memory tests to account for the difference between men and women in order to improve our accuracy in diagnosis,” said Sundermann.

Sundermann, PhD, of Albert Einstein College of Medicine in Bronx, NY, “One way to interpret the results is that because women have better verbal memory skills than men throughout life, women have a buffer of protection against loss of verbal memory before the effects of Alzheimer’s disease kick in. Because verbal memory tests are used to diagnose people with Alzheimer’s disease and its precursor, mild cognitive impairment, these tests may fail to detect mild cognitive impairment and Alzheimer’s disease in women until they are further along in the disease.”The study included participants from the Alzheimer’s Disease Neuroimaging Initiative: 235 people with Alzheimer’s disease, 694 people with mild cognitive impairment that included memory problems, and 379 people with no memory or thinking problems. The groups’ performance on a test of verbal memory was compared to the size of the hippocampal area of the brain, which is responsible for verbal memory and affected in the early stages of Alzheimer’s disease.

Boko Haram fear sees 30,000 flee Nigerian town: UN

first_imgNigerian troops capture Boko Haram commander Nigerian War Planes Strike Boko Haram Boko Haram: Nigerian Army Atrocities Uncoveredcenter_img Boko Haram Fighters [File Photo]More than 30,000 people have fled the northeast Nigerian town of Rann and across the border to Cameroon  because of fears of renewed Boko Haram attacks, the UN, civilian militia and residents said on Tuesday.UN refugee agency spokesman Babar Baloch told reporters in Geneva that recent fighting in Borno had forced more than 80,000 people to flee their homes.“Nigerian refugees continue to arrive in very remote and impoverished communities in neighbouring countries,” he added.“All the population seems to be panicking and they are on the run as a preemptive measure to save their lives.”The latest mass movement comes as the world body voiced renewed concern about the effect of the bloody conflict on civilians and launched a longer-term plan to help those made homeless by the fighting.Rann, in northern Borno state, near the border with Cameroon, has been repeatedly attacked by Boko Haram, most recently on January 14, when the jihadists targeted a military base.Humanitarian organisations working in Rann said the attack earlier this month forced some 9,000 people to flee into Cameroon.But they were sent back, as Cameroon deployed troops to reinforce the town as part of the regional military response against the Islamist militants.“It was a bit peaceful but as far as we understand now, that multinational taskforce has left,” said Baloch, adding that refugees had told aid workers Boko Haram “promised to return”.Walid Abdallahi, who was among those who fled, said there was now “not a single resident in Rann” and that Boko Haram had been “in control” of the town since Monday.“We all left the town as soon as the Cameroonian soldiers withdrew because we knew we were vulnerable to Boko Haram who would no doubt launch an attack,” he told AFP.Mr Abadallahi said the remaining Nigerian soldiers also withdrew “because their number was too small to face Boko Haram when they attacked”.His account was supported by an aid worker who left Rann after the January 14 attack but remains in contact with those in the area, and a civilian militia source.“There were over 35,000 IDPs (internally displaced people) in Rann and all of them have fled to Cameroon,” the aid worker added.According to the UN aid agencies’ access to people in hard-to-reach areas was largely unchanged in the last year, indicating security conditions had not improved.Many IDPs have had to move several times as a result of attacks and are unable to return home. An average of 4,500 people were displaced every week in 2018, it added.Relatedlast_img read more
