The analysis discovered that damages to these synaptic connections between neurons could be caused by chronic stress, but with an individual dose of ketamine, the damage could be rapidly reversed. This system differs from that of antidepressant medications, which have an effect on different neurotransmitters – – chemical messengers between neurons – – like serotonin. Based on the Mayo Clinic, frequently recommended antidepressants like Prozac and Zoloft block the brain’s reabsorption of serotonin and help brain cells send and receive chemical messages, which in turn boosts mood. But about one in three people acquiring antidepressants don’t display improved symptoms despite taking them for months, according to the researchers.Dr Susanne Sorensen, head of analysis at the Alzheimer’s Culture, said: It is crucial that we have a apparent picture of the medial side effects of drugs commonly taken by the elderly with cognitive impairment and other conditions. This robust study provides valuable results, and must be taken seriously. Nonetheless it is vital that people do not panic or stop acquiring their medicine without consulting their GP. We would urge people to possess regular appointments with their doctor to examine all prescription drugs they are acquiring.
