researchers in Stanford University A recent study revealed a new category of depression called “cognitive subtypes.” According to the study, approximately 27 percent of diagnosed patients suffer from this unique form of depression, which has characteristics very similar to those of attention deficit disorder.
The findings were published in New York postal, It was also emphasized that standard antidepressants are not effective in treating this particular type of depression.
The study, based on a randomized clinical trial involving more than 1,000 adults, aimed to balance serotonin levels in the brain, which many researchers believe contributes to depression. However, the researchers found that only 38 percent of those diagnosed with the cognitive subtype experienced remission of symptoms, compared with nearly 48 percent of those without the cognitive subtype.
Lead author Leanne Williams highlights the need to find new ways to address the challenges faced by people with this cognitive subtype of depression. The traditional trial-and-error process of treatment needs to be improved to ensure more people can recover more effectively.
The Washington Post quoted Williams as saying: “One of the biggest challenges is to find a new way to solve the current trial and error process so that more people can recover more quickly.”
The researchers believe the finding is the first instance of a “clinically actionable cognitive biotype for depression.” Their findings suggest that cognitive impairment is not only a consequence of depression, but may also be a contributing factor to the development of depression.
The identification of this cognitive subtype of depression represents a major breakthrough in understanding and treating the complexities of depression. It highlights the limitations of treatment of serotonin levels in the brains of patients with cognitive impairment by conventional antidepressants.
