It seems their poorer outcomes may be at least partially due to the lower expectations of their teachers; national data show teachers hold expectations for students labeled with learning disabilities that are inconsistent with their academic potential (as evidenced by test scores and learning behaviors). It has been said that there is a strong connection between children with a learning disability and their educational performance.Many studies have been done to assess the correlation between learning disability and self-esteem. These studies have shown that an individuals self-esteem is indeed affected by their own awareness of their learning disability. Students with a positive perception of their academic abilities generally tend to have higher self-esteem than those who do not, regardless of their actual academic achievement. However, studies have also shown that several other factors can influence self-esteem. Skills in non-academic areas, such as athletics and arts, improve self-esteem. Also, a positive perception of ones physical appearance has also been shown to have positive effects of self-esteem. Another important finding is that students with learning disabilities are able to distinguish between academic skill and intellectual capacity. This demonstrates that students who acknowledge their academic limitations but are also aware of their potential to succeed in other intellectual tasks see themselves as intellectually competent individuals, which increases their self-esteem.Research involving individuals with learning disabilities who exhibit challenging behaviors who are subsequently treated with antipsychotic medications provides little evidence that any benefits outweigh the risk.
Orbital lymphoma is a common type of non-Hodgkin lymphoma that occurs near or on the eye. Common symptoms include decreased vision and uveitis. Orbital lymphoma can be diagnosed via a biopsy of the eye and is usually treated with radiotherapy or in combination with chemotherapy. Types
There are two main types of intraocular lymphomas: primary central nervous system involvement (PCNSL) and primary central nervous system with ocular involvement (PCNSLO). The difference between PCNSL and PCNSLO is that PNSCL involves the central nervous system, while PCNSLO does not. 56-86% of orbital lymphomas are classified PCNSL and 15-25% are classified PCNSLO.PCNSLO is common in people who are severely immunosuppressed. Symptoms of this form of ocular lymphoma include painless decreased vision, sensitivity to light, a red eye, and floaters. Diagnosis is difficult due to its gradual onset and the fact that the symptoms are the same as other diseases. PCNSLO is usually bilateral, but sometimes grows unevenly. Like other metastatic tumors of the eye, it is usually confined to the choroid. Signs and symptoms
Primary visible signs of ocular lymphoma include proptosis and a visible mass in the eye. Symptoms are due to mass effect. Pathophysiology
Recent studies have detected the presence of viral DNA in ocular lymphoma cells. This implies that pathogens play a role in ocular lymphoma. Other studies have found that the aging population, the increasing number of immunosuppressive drugs, and the AIDS epidemic have also contributed to the increased incidence of Non-Hodgkin lymphomas.
