An alternative explanation is that the efficacy of MIT depends on neural circuits involved in the processing of rhythmicity and formulaic expressions (examples taken from the MIT manual: "I am fine," "how are you?" or "thank you"); while rhythmic features associated with melodic intonation may engage primarily left-hemisphere subcortical areas of the brain, the use of formulaic expressions is known to be supported by right-hemisphere cortical and bilateral subcortical neural networks.Systematic reviews support the effectiveness and importance of partner training. According to the National Institute on Deafness and Other Communication Disorders (NIDCD), involving family with the treatment of an aphasic loved one is ideal for all involved, because while it will no doubt assist in their recovery, it will also make it easier for members of the family to learn how best to communicate with them.When a persons speech is insufficient, different kinds of augmentative and alternative communication could be considered such as alphabet boards, pictorial communication books, specialized software for computers or apps for tablets or smartphones. Intensity of treatment
The intensity of aphasia therapy is determined by the length of each session, total hours of therapy per week, and total weeks of therapy provided. There is no consensus about what "intense" aphasia therapy entails, or how intense therapy should be to yield the best outcomes.
Tay–Sachs disease belongs to the latter. Other
Other lipid storage disorders that generally are not classified as sphingolipidoses include fucosidosis, Schindler disease, and Wolman disease. Genetics
Lipid storage diseases can be inherited two ways:
Autosomal recessive inheritance occurs when both parents carry and pass on a copy of the faulty gene, but neither parent show signs and symptoms of the condition and is not affected by the disorder. Each child born to these parents have a 25 percent chance of inheriting both copies of the defective gene, a 50 percent chance of being a carrier, and a 25 percent chance of not inheriting either copy of the defective gene. Children of either gender may be affected by an autosomal recessive this pattern of inheritance.X-linked recessive (or sex linked) inheritance occurs when the mother carries the affected gene on the X chromosome that has determined the childs gender and passes it to her son. Sons of carriers have a 50 percent chance of inheriting the disorder. Daughters have a 50 percent chance of inheriting the X-linked chromosome, but usually are not severely affected by the disorder. Affected men do not pass the disorder to their sons, but their daughters will be carriers for the disorder. Diagnosis
Diagnosis of the lipid storage disorders can be achieved through the use of several tests. These tests include clinical examination, biopsy, genetic testing, molecular analysis of cells or tissues, and enzyme assays. Certain forms of this disease also can be diagnosed through urine testing, which detects the stored material.
