Presence of a benediction sign when attempting to form a fist, due to weakness in flexion of radial half of digits
Sensory deficit: Loss of sensation in lateral 3+1⁄2 digits including their nail beds, and the thenar areaWithin the wrist: Carpal tunnel syndrome

Common mechanism: Carpal tunnel syndrome, an injury by compression in the carpal tunnel, without transection of the median nerve, due to overuse by activities such as keyboard typing and cooking
Motor deficit:
Weakness in flexion of radial half of digits and thumb, weakness in abduction and opposition of thumb
Presence of an ape hand deformity or when attempting to form a fist, the benediction sign, due to compression of the median nerve, as opposed to complete median nerve palsy
Sensory deficit: Numbness and tingling in lateral 3+1⁄2 digits including their nail beds, but excluding the thenar eminence which is supplied by the palmar cutaneous branch of the median nerve Unlike in wrist laceration,  sensation still occurs in the area of the central palm. Sensation is not lost because the palmar cutaneous branch runs above the flexor retinaculum, and is not affected in compression in carpal tunnel syndrome. Additional images

In contrast, pooled second-generation antipsychotics showed superiority to first-generation antipsychotics only against the discontinuation, negative symptoms (with a much larger effect seen among industry- compared to government-sponsored studies), and cognition scores. Olanzapine caused less extrapyramidal side effects and less akathisia, but caused significantly more weight gain, serum cholesterol increase, and triglyceride increase than haloperidol.A 2012 review concluded that among ten atypical antipsychotics, only clozapine, olanzapine, and risperidone were better than first-generation antipsychotics. A 2011 review concluded that neither first- nor second-generation antipsychotics produce clinically meaningful changes in CGI scores, but found that olanzapine and amisulpride produce larger effects on the PANSS and BPRS batteries than five other second-generation antipsychotics or pooled first-generation antipsychotics. A 2010 Cochrane systematic review found that olanzapine may have a slight advantage in effectiveness when compared to aripiprazole, quetiapine, risperidone, and ziprasidone. No differences in effectiveness were detected when comparing olanzapine to amisulpride and clozapine. A 2014 meta-analysis of nine published trials having minimum duration six months and median duration 52 weeks concluded that olanzapine, quetiapine, and risperidone had better effects on cognitive function than amisulpride and haloperidol. Bipolar disorder
Olanzapine is recommended by the National Institute for Health and Care Excellence as a first-line therapy for the treatment of acute mania in bipolar disorder. Other recommended first-line treatments are haloperidol, quetiapine, and risperidone.
