A baseline motor assessment establishes the starting point for developmental intervention programs. Comparing children to normal rates of development may help to establish areas of significant difficulty. However, research in the British Journal of Special Education has shown that knowledge is severely limited in many who should be trained to recognise and respond to various difficulties, including developmental coordination disorder, dyslexia and deficits in attention, motor control and perception (DAMP). The earlier that difficulties are noted and timely assessments occur, the quicker intervention can begin. A teacher or GP could miss a diagnosis if they are only applying a cursory knowledge. "Teachers will not be able to recognise or accommodate the child with learning difficulties in class if their knowledge is limited. Similarly GPs will find it difficult to detect and appropriately refer children with learning difficulties." A diagnosis of DCD is reached only in the absence of other neurological impairments such as cerebral palsy, multiple sclerosis, or Parkinsons disease. Classification
Developmental coordination disorder is classified in the fifth revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) as a motor disorder, in the category of neurodevelopmental disorders. Prevalence
The exact proportion of people with the disorder is unknown since the disorder can be difficult to detect due to a lack of specific laboratory tests, thus making diagnosis of the condition one of elimination of all other possible causes/diseases. Approximately 5–6% of children and adults are affected by this condition.
Nasopharyngeal angiofibroma is an angiofibroma also known as juvenile nasal angiofibroma, fibromatous hamartoma, and angiofibromatous hamartoma of the nasal cavity. It is a histologically benign but locally aggressive vascular tumor of the nasopharynx that  arises from the superior margin of the sphenopalatine foramen and grows in the back of the nasal cavity. It most commonly affects adolescent males (because it is a hormone-sensitive tumor). Though it is a benign tumor, it is locally invasive and can invade the nose, cheek, orbit (frog face deformity), or brain. Patients with nasopharyngeal angiofibroma usually present with one-sided nasal obstruction with profuse epistaxis. Signs and symptoms
Frequent chronic epistaxis or blood-tinged nasal discharge
Nasal obstruction and rhinorrhea
Facial dysmorphism (when locally invasive)
Conductive hearing loss from eustachian-tube obstruction
Diplopia, which occurs secondary to erosion into superior orbital fissure and due to third and sixth nerve palsy. Proptosis when having intraorbital extension. Rarely anosmia, recurrent otitis media, and eye pain. Diagnosis
If nasopharyngeal angiofibroma is suspected based on physical examination (a smooth vascular submucosal mass in the posterior nasal cavity of an adolescent male), imaging studies such as CT or MRI should be performed.
