The negative symptoms (Andreasen et al best 25mg promethazine allergy symptoms pressure in head, 1982; loss of personality features and abilities) are the most troublesome symptoms of the chronic phase of schizophrenia buy 25 mg promethazine overnight delivery allergy shots grass. The DSM-5 sub-classification is as follows: 1) Affect impairment (flattening or blunting) - diminished emotional expression purchase promethazine 25 mg otc allergy testing elizabethtown ky, with reduced expression of emotion in the face, speech and bodily movements, 2) Anhedonia - reduced ability to experience pleasure, reduced interpersonal skills, 3) Asociality – apparent lack of interest in social interaction, 4) Avolition (apathy) - reduced self-initiated purposeful activities, 5) Alogia – diminished speech output (this is another view of poverty of speech, discussed in Chapter 6). While the negative symptoms are regarded as the predominant feature of the chronic phase, they may be detected as early as the first psychotic episode. Some researchers found that certain symptoms did not easily fit into the two category model, and developed a three category/factor model (Bilder et al, 1985). Along with the positive and negative symptom groups, a third group was designated “disorganisation” - this included some thought disorder, bizarre behaviour, impaired attention and some cognitive dysfunction. A range of other ways of grouping the symptoms of schizophrenia have been suggested, but will not be described. Medical students only require knowledge of the positive/negative symptom division; those wanting to do exceptionally well in psychiatry should be aware the third set of disorganized symptoms/cognitive dysfunction. Symptoms (Psychotic/acute) Hallucinations See Chapter 5. These items were kept by a young man with schizophrenia. He was socially isolated and secretive and brought to hospital by his parents. His parents explained that he had written “Cursing Jar For Good” on the lid of this jar, and had written multiple “curses” concerning “enemies” which he placed inside. His parents told that he behaved as if these curses were a serious matter, and he expected them to be effective. While not proof, this activity was highly suggestive of psychosis. The idea of a “cursing jar” appeared to have come from the fashion of maintaining a “cussing jar” in work-places and pubs, into which people were obligated to place money if they “cussed” (cursed/swore) – at intervals the contents to be donated to charity or similar “good” cause. The evidence suggested the patient believed he could cast spells or curses on other people (delusion). This was not appropriate in his culture and suggested a delusion. A well groomed young man (clothes in the background) was brought to hospital. When staff unpacked his belongings, they found a bag of human faeces. When he recovered, the patient explained he had believed his faeces contained gold dust, which he had intended to extract. The delusions described above are spectacular – the majority are far less so. Form of thought – Formal Thought Disorder (FTD) See Chapter 6. As mentioned above, derailment, incoherence and neologisms are ranked with the positive symptoms, while poverty of thought is ranked with the negative symptoms. Symptoms (Negative/chronic) The symptoms mentioned in DSM-5 will be discussed first. Accordingly, the mood disorders of current times [depression/mania] are still sometimes referred to as “affective” disorders, but this is not recommended. In examination of the mental state, the term affect refers to “the external manifestation of the internal feeling state”. It is said that affect is to mood as weather is to climate, introducing the notion of immediacy and brevity. In our interactions with others we expect some “emotional contact”, interest or personal warmth.

In late-stage HD purchase 25 mg promethazine mastercard allergy shots vertigo, patients typically become akinetic and largely nonverbal order 25mg promethazine with mastercard allergy medicine 14 month old, with severe rigidity and joint contractures order 25mg promethazine with visa allergy shots help eczema.

Severe irritability is another common symptom, present in one-third of patients in the Maryland HD survey (2). Irritability and aggression may occur in patients without a prior history of a short temper, but these symptoms are more common in patients who have had these traits all their lives. Apathy may become evident at any time in the course of the disease. Either apathy or irrita- bility may exist independently or as part of an affective syndrome. Patients with HD occasionally develop classic obsessive- compulsive disorder, with typical symptoms such as fear of contamination or excessive hand washing. The percentage of patients however, patients may display an obsessive preoccupation surviving as a function of years since disease onset.

In this stable environment the patient can be closely observed purchase promethazine 25mg overnight delivery allergy testing kent, investigations can be conducted to exclude intracranial pathology and other psychiatric disorders (mania buy promethazine 25 mg low cost allergy easy, substance misuse order 25mg promethazine fast delivery allergy steroid shot, personality disorder), and the correct diagnosis can be confirmed. Acute treatment reduces the risks of self harm, and may be necessary for the protection of others. Acute treatment relieves the suffering of the patient. High standard nursing care is imperative for the best outcome. The patient and family must be provided with comprehensive information about the disorder, management aims and methods, and community follow-up options – but this, in itself, is not an argument for admission. Pharmacological intervention is mandatory, using (at least initially) an atypical antipsychotic medication (dopamine and serotonin receptor blockers) such as risperidone, olanzapine, quetiapine or aripirazole. Medication is considered in more detail in Chapter 15. The patient needs to feel secure and to be provided with a rational explanation so as to understand and challenge symptoms. Discharge from the acute hospital may be to a rehabilitation facility or to home. Rehabilitation may take the form of social skills training, stress coping strategies, life enriching activities, and assistance toward gainful employment. There is some evidence that cognitive rehabilitation training prevents delays/prevents relapse (Tao et al, 2015). Work with the family aims to create situations in which the patient is encouraged to be active, with a minimum of stress and interpersonal conflict. On discharge from hospital the patient should have regular medical review. Regular contact with a community based mental health worker who can review and respond appropriately to eventualities, is highly recommended. Regular medication should continue for at least 6 months after the first acute episode. Prevention There is strong interest in the prevention of the psychotic phase of schizophrenia. Prevention efforts at the moment focus on people who appear to be at risk of schizophrenia either because of genetic factors (being closely related to a person with schizophrenia, or because of suggestive features, such as personality change). However, there are difficulties in identifying which individuals will progress to psychosis, and the field is in its infancy. Brief psychiatric rating scale (BPRS) The purpose of rating scales is not to make a diagnosis, but to quantify signs and symptoms (and provide a basis of assessing severity and progress). The BPRS (Overall & Gorman, 1962) was one of the first rating scales developed for use in people with severe psychiatric disorders. He was exceptionally clever at physics and mathematics and was to commence at University in a few weeks. His mother was a science teacher; his father was a pharmacist. He had some male and female friends and took no illegal drugs. Over six weeks Phil had become isolative and hostile. In the days before the following interchange, it became clear that he had a delusion about bikies threatening him, and was experiencing auditory hallucinations which he believed was the voice of Stephen Hawking.
