Quick summary:
alien hand syndrome is usually a condition resulting from brain injury, often with the corpus callosum, frontal- or posterior lobe problems.

to have an association with multiple psychology- and/or health related themes;
a solid assessment always requires a consideration of hand sign combinations!
