Final answer:
The major side effect of Electroconvulsive Therapy (ECT) when used frequently is memory loss, which can affect both short-term and long-term memory. Confusion and physical discomfort may also occur after treatments, but ECT is generally not associated with insomnia, depression, or prostate enlargement.
Step-by-step explanation:
The major side effect of Electroconvulsive Therapy (ECT) when used frequently is memory loss. While ECT is an effective treatment for certain psychiatric conditions, it can have side effects, some of which can be serious. Memory loss is one of the most commonly cited side effects, particularly when ECT is administered over a prolonged period. This effect can vary in severity, affecting both short-term and long-term memory.
Other side effects of ECT can include confusion shortly after treatment, physical side effects such as headaches or muscle aches, and more rarely, long-lasting memory issues. However, the side effects such as insomnia, depression, or prostate enlargement mentioned in a second source are not typically associated with ECT and may pertain to side effects of medications or other treatments.
It is crucial for individuals considering ECT to discuss the potential risks and benefits with their healthcare provider and to be aware of the side effects that could arise from the treatment including the possibility of memory changes.
