Depression does not make a person inherently stupid. However, it can affect cognitive functioning and lead to difficulties in concentration, memory, decision-making, and problem-solving. These cognitive impairments are often referred to as "cognitive deficits."
When someone is experiencing depression, they may feel overwhelmed, fatigued, and lack motivation, which can interfere with their ability to think clearly and perform tasks effectively. This can lead to a sense of mental slowness or a decrease in cognitive sharpness.
The cognitive effects of depression can vary in severity from person to person and may improve as the depression is treated and the individual's mood lifts. It's essential to seek professional help if you or someone you know is experiencing symptoms of depression, as it is a treatable condition with therapy, medication, or a combination of both. Early intervention can help prevent the condition from worsening and can improve cognitive functioning over time.
