<p>Women who have their ovaries removed before <a href="https://www.mid-day.com/lifestyle/health-and-fitness/photo/in-photos-going-through-menopause-here-are-five-tip-to-follow-for-optimal-health-100723/1" rel="none"><strong>menopause</strong></a>, particularly before the age of 40, have reduced white matter integrity in multiple regions of the brain later in life, a new study said on Thursday.&nbsp;</p>
<p>White matter refers to the nerve fibres that connect neurons in different areas of the brain.</p>
<p>In the study published in the journal Alzheimer's &amp;amp; Dementia, the researchers analysed data from the Mayo Clinic Study of Aging to identify women over the age of 50 with available diffusion tensor imaging, a magnetic resonance imaging (MRI) technique that measures white matter in the brain.</p>
<p>"We know that having both ovaries removed before natural menopause causes abrupt endocrine dysfunction, which increases the risk of cognitive impairment and dementia," said Michelle Mielke, PhD, professor at the US-based Wake Forest University School of Medicine.</p>
<p>Researchers found that females who had premenopausal bilateral oophorectomy (PBO) before the age of 40 had significantly reduced <a href="https://www.mid-day.com/mumbai/mumbai-news/article/doesn-t-matter-if-you-are-black-or-white-60536" rel="none"><strong>white matter</strong></a> integrity in multiple regions of the brain.</p>
<p>"There were also trends in some brain regions such that women who had PBO between the ages of 40-44 or 45-49 years also had reduced white matter integrity, but many of these results were not statistically significant," said Mielke.</p>
<p>She also said that 80 per cent of participants who had their ovaries removed also had a history of estrogen replacement therapy.</p>
<p>Therefore, the study was not able to determine whether the use of estrogen replacement therapy after PBO mitigated the effects of PBO on white matter integrity.</p>
<p>"Having both ovaries removed results in an abrupt decrease in both <a href="https://www.mid-day.com/lifestyle/relationships/article/Young-man--older-woman--Relationship-rules-changing-in-India-23197310" rel="none"><strong>estrogen</strong></a> and testosterone in women. Therefore, one possible explanation for our results is the loss of both estrogen and testosterone," Mielke mentioned.</p>
