Brain stimulation treatments, like electroconvulsive therapy (ECT) and transcranial magnetic stimulation (TMS), are often effective for the treatment of depression. Like antidepressant medications, however, they typically have a delayed onset. For example, a patient may receive several weeks of regular ECT treatments before a full response is achieved.

Patients who have a clot in their legs and are considering whether to be treated with traditional blood-thinning medication or undergo a minimally-invasive catheter-based clot removal procedure should feel comfortable that there is no difference in death rates between the two treatments, although there are more bleeding risks with the catheter procedure, according to a study by Temple University School of Medicine researchers.
The seriousness of disease often results from the strength of immune response, rather than with the virus, itself.
