Overall, extreme weather events appear to have a "magnifying effect" in exacerbating the underlying prevalent mental and physical health conditions of homeless populations. Case study: Hurricane Katrina
In 2005, Hurricane Katrina, a category 5 hurricane, made landfall on Florida and Louisiana. It particularly affected the city of New Orleans and the surrounding areas. Hurricane Katrina was the deadliest hurricane in the US in seven decades, with more than 1,600 confirmed deaths, and more than 1,000 people missing. The hurricane disproportionately affected marginalized individuals, and individuals with lower socioeconomic status (i.e., 93% of shelter residents were African–American, 32% had household incomes below $10,000/year and 54% were uninsured). The storm nearly doubled the number of homeless people in New Orleans. While in most cities, homeless people account for 1% of the population, in New Orleans, the homeless account for 4% of the population. In addition to its devastating effects on infrastructure and the economy, the estimated prevalence of mental illness and the incidence of West Nile Virus more than doubled after Hurricane Katrina in the hurricane-affected regions. Legal documentation
Homeless people may find it difficult to document their date of birth or their address. Due to the fact that homeless people usually have no place to store possessions, they often lose their belongings, including identification and other documents, or find them destroyed by police or others. Without a photo ID, homeless persons cannot get a job or access many social services, including healthcare.
Dysequilibrium syndrome may refer to:

Cerebellar ataxia, mental retardation, and dysequilibrium syndrome 1 (CAMRQ1), an autosomal recessive cerebellar ataxia associated with the VLDLR gene
Cerebellar ataxia, mental retardation, and dysequilibrium syndrome 2 (CAMRQ2), an autosomal recessive cerebellar ataxia associated with the WDR81 gene
Cerebellar ataxia, mental retardation, and dysequilibrium syndrome 3 (CAMRQ3), an autosomal recessive cerebellar ataxia associated with the CA8 gene
Cerebellar ataxia, mental retardation, and dysequilibrium syndrome 4 (CAMRQ4), an autosomal recessive cerebellar ataxia associated with the ATP8A2 gene
