[57]Although it may seem that people living with brain damage have great difficulty continuing the usual day-to-day aspects, they still can accomplish many feats. People with RA are able to lead a normal life. For instance, KC is a man who has many functional aspects intact; normal intelligence, unaffected perceptual and linguistic skills, short-term memory, social skills, and reasoning abilities. All of these things are necessary in everyday life and contribute to normal living. KC also is fully capable of scripted activities (e.g., making reservations or changing a flat tire). In addition, patient HC successfully graduated high school and continued into post-secondary studies, an obvious accomplishment despite her condition. DH relearned his childhood memories from his parents and can retell the stories, but cannot recall specifics other than what has been told to him. Other forms of amnesia
Other forms of amnesia exist and may be confused with RA. For instance, anterograde amnesia (AA) is the inability to learn new information. This describes a problem encoding, storing, or retrieving information that can be used in the future. It is important to note that these two conditions can, and often do both occur in the same patient simultaneously, but are otherwise separate forms of amnesia. RA can also be an inherent aspect of other forms of amnesia, namely transient global amnesia (TGA). TGA is the sudden onset of AA and RA caused by a traumatic event, however it is short lived, typically lasting only 4 to 8 hours.
In short term clinical trials extrapyramidal effects, sedation, akathisia, nausea, dizziness, vomiting, anxiety, and constipation were observed. One review characterized the frequency of these events as "not greatly different from that seen in patient treated with placebo" but a second called the incidence of movement-related disorders "rather high".Regarding side effects, the label of cariprazine states, "The possibility of lenticular changes or cataracts cannot be excluded at this time. "Because cariprazine and its active metabolites have long half-lives, many healthcare professionals monitor for adverse effects up to several weeks after starting cariprazine. A longer monitoring period is also indicated for dosage changes, whether they represent an increase or a decrease, because elimination may take several weeks

Pharmacology
Pharmacodynamics
Unlike many antipsychotics that are D2 and 5-HT2A receptor antagonists, cariprazine is a D2 and D3 partial agonist It also has a higher affinity for D3 receptors. The D2 and D3 receptors are important targets for the treatment of schizophrenia, because the overstimulation of dopamine receptors has been implicated as a possible cause of schizophrenia. Cariprazine acts to inhibit overstimulated dopamine receptors (acting as an antagonist) and stimulate the same receptors when the endogenous dopamine levels are low. Cariprazines high selectivity towards D3 receptors could prove to reduce side effects associated with the other antipsychotic drugs, because D3 receptors are mainly located in the ventral striatum and would not incur the same motor side effects (extrapyramidal symptoms) as drugs that act on dorsal striatum dopamine receptors.
