It has been well documented, and it is certainly true, that depression can lead to
sleep problems. However, the reverse is also true; long-standing sleep problems can
often cause depression. In such a case, it is the sleep problem that needs to be
treated, not the depression. I have worked with many insomnia sufferers who had been
treated unsuccessfully with anti-depressant medication, electric shock therapy (ECT),
psychiatry and so forth, whose depression lifted as soon as they began to sleep better.
