A new diagnosis identifying a nonorganic basis of dysphagia is proposed in relation to behavioral conditioning processes and thereby labeled "conditioned dysphagia" (CD). Literature review of both animal and human studies documents that rapidly acquired and persistent avoidance responses are learned when autonomic functions are contiguous with traumatic physical events. Three case studies with primary diagnoses of TE fistula, congenital heart disease and pseudobulbar palsy demonstrated an association between CD and early childhood incidence of trauma involving the esophagus. Successful treatment was achieved by operant deconditioning therapy. Results of a pilot epidemiological study of 28 postpharyngeal flap surgery children and 47 controls showed significantly higher incidence of mild to moderate CD in the surgery group.

Pathologically, Binswanger's disease is subcortical periventricular leucoencephalopathy sparing the U fibers. Clinically it is characterised by executive dysfunction, gait problems, urinary incontinence, pseudobulbar palsy, mood disturbances and dementia. The pathomechanism of Binswanger's disease is unclear. It is hypothesized that it results from an ischemic-hypoxic injury of the periventricular white matter, which, in turn, can be caused by a sclerotic elongation of the medullary arteries, widening of the perivascular spaces or decreased brain perfusion due to hypotension or heart disease. The symptoms of Binswanger's disease frequently overlap with those of normal pressure hydrocephalus, vascular parkinsonism and Alzheimer's disease. A diagnostic criterion of Binswanger's disease is radiologically demonstrated leukoaraiosis, which, on the other hand, is not equivalent with Binswanger's disease. A good clinical response after lumbar puncture or shunt implantation might lead to confusion with normal pressure hydrocephalus, which further complicates the clinical diagnosis. It is likely that among the above mentioned disorders there are a number of transitional forms and overlaps, which might be explained by the common pathomechanism of disturbance in cerebrospinal fluid circulation.
