Ans - Homelessness - Homelessness is defined as living in housing that is below the minimum standard or lacks secure tenure. People can be categorized as homeless if they are: living on the streets (primary homelessness); moving between temporary shelters, including houses of friends, family and emergency accommodation (secondary homelessness); living in private boarding houses without a private bathroom or security of tenure (tertiary homelessness). Homelessness satisfies the first rung in Maslow's Hierarchy of Needs, primarily due to their lack of adequate fundamental resources, including food, shelter, and water. The legal definition of homeless varies from country to country, or among different jurisdictions in the same country or region. According to the UK homelessness charity Crisis, a home is not just a physical space: it also provides roots, identity, security, a sense of belonging and a place of emotional well being. United States government homeless enumeration studies[5][6] also include people who sleep in a public or private place not designed for use as a regular sleeping accommodation for human beings. People who are homeless are most often unable to acquire and maintain regular, safe, secure and adequate housing due to an unsteady or lack of income. Homelessness and poverty are interrelated. There is no methodological consent on counting the homeless and identifying their special needs; thus in most cities only estimated homeless populations are known.
When compared to the general population, people who are homeless experience higher rates of adverse physical and mental health outcomes. Chronic disease severity, respiratory conditions, rates of mental health illnesses and substance use are all often greater in homeless populations than the general population. Homelessness is also associated with a high risk of suicide attempts. People experiencing homelessness have limited access to resources and are often disengaged from health services, making them that much more susceptible to extreme weather events (e.g., extreme cold or heat) and ozone levels. These disparities often result in increased morbidity and mortality in the homeless population.
Schizophrenia - Schizophrenia is a mental illness characterized by continuous or relapsing episodes of psychosis. Major symptoms include hallucinations (often hearing voices), delusions (having beliefs not shared by others), and disorganized thinking. Other symptoms include social withdrawal, decreased emotional expression, and lack of motivation. Symptoms typically come on gradually, begin in young adulthood, and in many cases never resolve. There is no objective diagnostic test; diagnosis is based on observed behavior, a history that includes the person's reported experiences, and reports of others familiar with the person. To be diagnosed with schizophrenia, symptoms and functional impairment need to be present for six months, (DSM-5), or one month, (ICD-11). Many people with schizophrenia have other mental disorders that often includes an anxiety disorder such as panic disorder, an obsessive–compulsive disorder, or a substance use disorder.
The causes of schizophrenia include genetic and environmental factors. Genetic factors include a variety of common and rare genetic variants. Possible environmental factors include being raised in a city, cannabis use during adolescence, infections, the ages of a person's mother or father, and poor nutrition during pregnancy . Diagnosed with schizophrenia will have a significant improvement over the long term with no further relapses, and a small proportion of these will recover completely. The other half will have a lifelong impairment, and severe cases may be repeatedly admitted to hospital. Social problems such as long-term unemployment, poverty, homelessness, exploitation, and victimization are common consequences of schizophrenia. Compared to the general population, people with schizophrenia have a higher suicide rate and more physical health problems, leading to an average decreased life expectancy of 20 years. The mainstay of treatment is an antipsychotic medication, along with counselling, job training, and social rehabilitation. Up to a third of people do not respond to initial antipsychotics, in which case the antipsychotic clozapine may be used. In situations where there is a risk of harm to self or others, a short involuntary hospitalization may be necessary. Long-term hospitalization may be needed for a small number of people with severe schizophrenia. In countries where supportive services are limited or unavailable, long-term hospital stays are more typical.
