What are the early symptoms of catatonic schizophernia?

Odd ideas, voices: Schizophrenia usually first shows in late teens or early 20s with social withdrawal and odd ideas that don't make sense to others. Auditory hallucinations (imaginary voices) are common too, although the person may not admit to hearing them. Self-care (hygiene, grooming) suffer, as well as school or work performance. Catatonia — stupor, immobility, posturing — is not usually an early symptom.

Catatonic: Flat affect, no motivation, limited speech, anhedonia, inattention, social withdrawal, disorganization, bizarre.
