The localization of lesions in areas of the frontal and temporal lobes would provide explanation for the difficulty in motor planning seen in ideational apraxia, as well as its difficulty to distinguish it from certain aphasias.Constructional apraxia is often caused by lesions of the inferior nondominant parietal lobe, and can be caused by brain injury, illness, tumor, or other condition that can result in a brain lesion. Diagnosis
Although qualitative and quantitative studies exist, little consensus exists on the proper method to assess for apraxia. The criticisms of past methods include failure to meet standard psychometric properties and research-specific designs that translate poorly to nonresearch use.The Test to Measure Upper Limb Apraxia (TULIA) is one method of determining upper limb apraxia through the qualitative and quantitative assessment of gesture production. In contrast to previous publications on apraxic assessment, the reliability and validity of TULIA was thoroughly investigated. The TULIA consists of subtests for the imitation and pantomime of nonsymbolic ("put your index finger on top of your nose"), intransitive ("wave goodbye"), and transitive ("show me how to use a hammer") gestures. Discrimination (differentiating between well- and poorly performed tasks) and recognition (indicating which object corresponds to a pantomimed gesture) tasks are also often tested for a full apraxia evaluation.However, a strong correlation may not be seen between formal test results and actual performance in everyday functioning or activities of daily living (ADLs).
Diphenoxylate/atropine, also known as co-phenotrope, is a combination of the medications diphenoxylate and atropine, used to treat diarrhea. It should not be used in those in whom Clostridioides difficile infection is a concern. It is taken by mouth. Onset is typically within an hour.Side effects may include abdominal pain, angioedema, glaucoma, heart problems, feeling tired, dry mouth, and trouble seeing. It is unclear if use in pregnancy is safe and use when breastfeeding may result in side effects in the baby. It works by decreasing contractions of the bowel.The combination was approved for medical use in the United States in 1960. It is available as a generic medication. In 2019, it was the 339th most commonly prescribed medication in the United States, with more than 900 thousand prescriptions. It is sold under the brand name Lomotil among others. The medication is in Schedule V in the United States. Contraindications
Absolute contraindications are:
Patients under 6 years of age
Allergy to diphenoxylate or atropine
Diarrhea associated with pseudomembranous enterocolitis, diarrhea caused by antibiotic treatment, or diarrhea caused by enterotoxin-producing bacteria, such as Clostridium difficile
Obstructive jaundice

Side effects
The drug combination is generally safe in short-term use and with recommended dosage. In doses used for the treatment of diarrhea, whether acute or chronic, diphenoxylate has not produced addiction. It may cause several side-effects, such as dry mouth, headache, constipation and blurred vision. Since it may also cause drowsiness or dizziness, it should not be used by motorists, operators of hazardous machinery, etc. It is not recommended for children under two years of age.
