Ingestion of cat feces containing oocysts: This can occur through hand-to-mouth contact following gardening, cleaning a cats litter box, contact with childrens sandpits; the parasite can survive in the environment for months. Ingestion of untreated, unfiltered water through direct consumption or utilization of water for food preparation. Ingestion of unpasteurized milk and milk products, particularly goats milk. Ingestion of raw seafood.Cats excrete the pathogen in their feces for a number of weeks after contracting the disease, generally by eating an infected intermediate host that could include mammals (like rodents) or birds. Oocyst shedding usually starts from the third day after ingestion of infected intermediate hosts, and may continue for weeks. The oocysts are not infective when excreted. After about a day, the oocyst undergoes a process called sporulation and becomes potentially pathogenic. In addition to cats, birds and mammals including human beings are also intermediate hosts of the parasite and are involved in the transmission process. However the pathogenicity varies with the age and species involved in infection and the mode of transmission of T. gondii.Toxoplasmosis may also be transmitted through solid organ transplants. Toxoplasma-seronegative recipients who receive organs from recently infected Toxoplasma-seropositive donors are at risk. Organ recipients who have latent toxoplasmosis are at risk of the disease reactivating in their system due to the immunosuppression occurring during solid organ transplant.
Borderline intellectual functioning, also called borderline mental retardation (in the ICD-8), is a categorization of intelligence wherein a person has below average cognitive ability (generally an IQ of 70–85), but the deficit is not as severe as intellectual disability (below 70). It is sometimes called below average IQ (BAIQ). This is technically a cognitive impairment; however, this group may not be sufficiently mentally disabled to be eligible for specialized services. Codes
The DSM-IV-TR code of borderline intellectual functioning is V62.89. DSM-5 diagnosis codes are V62.89 and R41.83. Learning skills
During school years, individuals with borderline intellectual functioning are often "slow learners". Although a large percentage of this group fails to complete high school and can often achieve only a low socioeconomic status, most adults in this group blend in with the rest of the population. Differential diagnosis
According to the DSM-5, differentiating borderline intellectual functioning and mild intellectual disability requires careful assessment of adaptive and intellectual functions and their variations, especially in the presence of co-morbid psychiatric disorders that may affect patient compliance with standardized test (for example, attention deficit hyperactivity disorder (ADHD) with severe impulsivity or schizophrenia).
