One of his personalities may have been psychopathic; but the brunt of his mental instability stemmed from multiple personality disorder...
So, in that context : no, I probably wouldn't know if a colleague or co-worker was psychopathic unless I was intimately close with them.
Also... "psychotic" refers to a different disorder known as psychosis... You mean psychopathic. Psychotics are simply delusional...
Psychosis (not to be confused with psychopathy) is a mental illness in which an individual divorces from reality due to distorted perceptions about what is actually taking place (including delusions or visual/auditory hallucinations). These delusions are defined as magnified deviations from commonly held beliefs, and can assimilate to form an alternate mental reality in which the psychotic inhabits. Disturbances in cognitive and sensual faculties produce a number of specific symptoms which are commonly associated with psychosis; though the distinctions between them and other illnesses such as neurosis or schizophrenia are still debated in reference to modern psychiatric classification systems. Nevertheless, the paradigm remains accepted because it encompasses relatively vague diagnosis standards; thus coping with varying individual cases - while being exact enough to distinguish itself from other mental ailments. Psychosis entails a number of causes, symptoms, treatments, and prognosis; all of which vary according to their contexts.
The onset of psychosis often begins with prior mental ailments or drug abuse (especially involving hallucinogens, PCP, amphetamines, cocaine, and marijuana); both of which may cause irreparable disruption to mental faculties or the nervous system. Psychosis is frequently assorted with the concept of brain degeneration or brain malformation. In addition, some contemporary psychologists theorize that biological changes and physiological abnormalities in the brain are the primary conductors of the illness. Therefore, psychosis could be the result of personality inflictions or jumbled thought processes induced by developmental disturbances or traumatic experiences. It has also been speculated that psychosis develops in adaptation to stress or undernourished child development. Preconditions such as dementia, manic depression, brain tumors, epilepsy, psychotic depression, and schizophrenia may also dilute perceptions enough to affect psychosis temporarily or permanently. Of course, these supposed causes cannot be identified by a medical physician without observable symptoms and medical evaluation.
Common warning signs of psychosis include numerous subdivisions which overlap other mental illnesses such as neurosis or schizophrenia. However, the overall conjunction of symptoms produces behaviors that are readily seen and identified as a whole; consequentially signaling a need for medical care. Psychosis manifests in the form of abnormal displays of emotion, confusion, depression, disjointed thoughts and speech, mania, false beliefs, loss of touch with reality, dysfunctional perceptions, visual/auditory hallucinations, unfounded fear or suspicion, catatonic behavior, vegetative states, or erratic physical tendencies. As a result, psychotics are somewhat difficult to empathize with in relation to the majority of society, despite the fact that they may have parallel experiences with most people. Therefore, it is deducible that exaggerated projections of reality are apparent for the psychotic, which is reflected by their emotionally charged or erratic behavior.
On the other hand, many of these symptoms are not always discernible in comparison to normal modes of thought; and there is often a multitude of etiological routes a practitioner may find when diagnosing psychosis. These factors can make identification of psychosis a daunting task for even a skilled clinician. Thorough psychological evaluation is necessary for such diagnostics, and may be reinforced by laboratory testing. In fact, methods such as drug screens, MRI, and syphilis tests are sometimes used to pinpoint exact biological causation behind psychosis, though they may not identify “functional” causation (manic-depression, schizophrenia, or other diagnostic criteria).
Upon diagnostic procedure, a physician may utilize an array of remedies for the mental illness which are selected for respective causes. Hospital care is often needed to guarantee the patients safety, while anti-psychotic drugs such as risperidone (Risperdal), thioridazine (Mellaril), halperidol (Haldol), chlorpromazine (Thorazine), clozapine (Clozaril), loxapine (Loxitane), molindone hydrochloride (Moban), thiothixene (Navane), and olanzapine (Zyprexa) subdue hallucinations and delusions. Treatments such as these help expunge harmful psychotic behavior. Recently, group therapy has been implemented for those who experience schizoid or psychotic symptoms, apparently reducing the likelihood of mental degeneration (suggesting that isolated individuals and families are more likely to develop and compound mental illnesses). New formed therapies such as these derive from cognitive behavioral approaches developed for neurotic disorders.
Even so, there are preventative measures one might take to avoid diagnosis and treatment simultaneously. For instance, one might heed alcohol abuse to prevent alcohol-induced psychosis – which is triggered by the depression of the nervous system. Alcohol abuse is discouraged in general, especially when mixed with medication, while hallucinogens and other drugs increase the likelihood of the user experiencing a psychotic attack. In addition, safe-sex practices and medication inhibit the contraction of syphilis, which can catalyze brain degradation or even death. Healthy social stimulation and interpersonal communication is also linked to brain development, especially within emerging families and communities. Therefore, gregariousness may help prevent psychotic tendencies.
Overall, the success of prognosis relies on the circumstance of the patient. Those who experience longer and more intense psychotic episodes may be less likely to receive beneficial results from extemporaneous treatment. One the other hand, earlier diagnosis and immediate treatment are more likely to produce a positive outcome for the patient by quelling the disease before it causes irreparable damage to the structure of the brain. Schizophrenia has a 60% treatment success rate , while, according to European studies, 50-80% of all patients have no further major psychiatric problems. Generally, prognosis of brief psychotic episodes often lasts approximately a month with a good success ratio.
