“Can a psychologist help schizophrenia?”

Yes. Understanding how this diagnosis is effecting your perception and how tension and stress effects you is essential. A psychotherapist can provide new skills and understanding to move them into better control.

Yes, but the psychologist cannot believe it's genetic. The psychologist also has to be sure that the parents are not in the picture anymore, or, if they are, the parents agree to take responsibility with the patient for their suffering. This means there can be moments when the patient tries to unravel the mixed messages the parents will be open to helping. Parents don't know better, but once the clues for cause are there, the parents become parents who would throw themselves under the bus for their child's sake or the other way around. There will be a failed or weak attachment in the first days or years of life. There will be issues with attunement with the baby s/he was, and likely insufficient touch and cuddling, followed by attachment breaks. There will be mixed messages or expectations that cannot be taken together, because to do one thing makes the other thing wrong. There will be pressure expressed or implied not to complain. There may be an element of blame to uncover. The patient will need to grapple with these mixed messages and early experiences without having to protect the parents. If that can't be done, there's no point in trying.
