Observation of functional activities might be carried at school and home as well.Though diagnosis in most of the world is done by an occupational therapist, in some countries diagnosis is made by certified professionals, such as psychologists, learning specialists, physiotherapists and/or speech and language therapists. Some countries recommend to have a full psychological and neurological evaluation if symptoms are too severe. Standardized tests

Classification
Sensory integration and processing difficulties
Construct-related evidence relating to sensory integration and processing difficulties from Ayres early research emerged from factor analysis of the earliest test the SCISIT and Mulligans 1998 "Patterns of Sensory Integration Dysfunctions: A Confirmatory Factor Analysis". Sensory integration and processing patterns recognised in the research support a classification of difficulties related to:

Sensory registration and perception (discrimination)
Sensory reactivity (modulation)
Praxis (meaning "to do")
Postural, ocular and bilateral integration

Sensory processing disorder (SPD)
Proponents of a new nosology SPD have instead proposed three categories: sensory modulation disorder, sensory-based motor disorders and sensory discrimination disorders (as defined in the Diagnostic Classification of Mental Health and Developmental Disorders in Infancy and Early Childhood). 1. Sensory modulation disorder (SMD)
Sensory modulation refers to a complex central nervous system process by which neural messages that convey information about the intensity, frequency, duration, complexity, and novelty of sensory stimuli are adjusted.SMD consists of three subtypes:

Sensory over-responsivity.
However several observational studies have identified the use of glucocorticoids as a factor associated with increased risk of VAP and other Hospital-acquired infections. References
