Presentation
Seizures may be present at birth or within the first month of life. Edema of the feet, hands, and face are also present at birth. Cognitive deficits and motor delays are usually evident during infancy. [disorders.eyes.arizona.edu]
Microcephaly is progressive and not usually present at birth. [nature.com]

Cerebellar and brainstem atrophy are usually present on neuroimaging. A PEHO-like syndrome has been described, in which the affected individuals have neither optic atrophy nor the typical neuroradiological findings. [digital.library.adelaide.edu.au]
Entire Body System
- Poor Feeding
General drowsiness and poor feeding are often features. Death usually occurs in infancy or early childhood. Midface hypoplasia and micrognathia are often present. [disorders.eyes.arizona.edu]
Clinical description Onset occurs during the first few weeks or months of life with hypotonia, poor feeding, drowsiness and abnormal movements. Infantile spasms, hypsarrhythmia and seizures appear during the first year of life. [rareguru.com]

Treatment
Treatment Treatment Options: Physical therapy to prevent contractures and general supportive care can be helpful. Supplemental feeding may be required. [disorders.eyes.arizona.edu]
Diagnosis Treatment There is no cure for PEHO syndrome. Some symptoms can be managed, but otherwise treatment is supportive care. References External links PEHO syndrome [owlapps.net]
(November 2020) Treatment[edit] There is no cure for PEHO syndrome. Some symptoms can be managed, but otherwise treatment is supportive care.[citation needed] References[edit] ^ OrphanNet. "PEHO syndrome". [en.wikipedia.org]
Management and treatment Treatment is symptomatic only. The infantile spasms are refractory to antiepileptic drugs or adrenocorticotropic hormone (ACTH) therapy. [rareguru.com]
Prognosis
Prognosis The prognosis is poor and most patients die before 15 years of age, mainly as a result of pneumonia or aspiration. Visit the Orphanet disease page for more resources. [rareguru.com]

This raises the possibility that some of the recurrences reported may be because of germline mosaicism or somatic mosaicism in one parent, and that PEHO syndrome is etiologically heterogeneous. [nature.com]
Functional MR imaging techniques including diffusion tensor imaging, perfusion-weighted imaging, and 1H-MR spectroscopy could be helpful for a better understanding of the etiology and progression of injury. [ajnr.org]
Epidemiology
Epidemiology The incidence in Finland has been estimated at 1 in 78 000, but a few patients have been described from other countries including (The Netherlands, Spain France). [rareguru.com]
Pathophysiology

Prevention

However, recent studies have provided evidence that insulin-like growth factor 1 (IGF-1) may prevent the NO-mediated neuronal damage and is essential for the survival of the cerebellar granule cells. These cells will degenerate in the PEHO syndrome. [findis.org]
The ADC values of the cortex could not be measured, because the high degree of cortical atrophy prevented a reliable positioning of a region of interest. [ajnr.org]
