1.Vascular Depression.
Journal of Korean Geriatric Psychiatry 2002;6(1):16-26
This article reviews the recent literature of 'vascular depression' hypothesis. The 'vascular depression' hypothesis is supported by the evidence for associations between vascular disease and late-onset depression and between ischemic brain lesions and distinctive depressive symptoms. Patients with vascular depression is characterized by late-onset, absence of family history of mood disorders, evidence of vascular disease or vascular risk factors, cognitive impairment, psychomotor retardation, limited depressive ideation, poor insight, and disability. Vascular depression may be the entity suitable for studies of mechanism of depression. Depression in later life is often under-diagnosed and under-treated. Drugs used in the prevention and treatment of cerebrovascular disease may be shown to be beneficial influences for the prevention of vascular depression. Combined treatment with antidepressant and cognitive-behavioral rehabilitation will be more helpful. In the future, developments in structural and functional imaging, electrophysiology, chronobiology, and genetics will permit the knowledge of the association between mood disorders and brain lesions.

2.Early-onset epileptic encephalopathies and the diagnostic approach to underlying causes.

Early-onset epileptic encephalopathies are one of the most severe early onset epilepsies that can lead to progressive psychomotor impairment. These syndromes result from identifiable primary causes, such as structural, neurodegenerative, metabolic, or genetic defects, and an increasing number of novel genetic causes continue to be uncovered. A typical diagnostic approach includes documentation of anamnesis, determination of seizure semiology, electroencephalography, and neuroimaging. If primary biochemical investigations exclude precipitating conditions, a trial with the administration of a vitaminic compound (pyridoxine, pyridoxal-5-phosphate, or folinic acid) can then be initiated regardless of presumptive seizure causes. Patients with unclear etiologies should be considered for a further workup, which should include an evaluation for inherited metabolic defects and genetic analyses. Targeted next-generation sequencing panels showed a high diagnostic yield in patients with epileptic encephalopathy. Mutations associated with the emergence of epileptic encephalopathies can be identified in a targeted fashion by sequencing the most likely candidate genes. Next-generation sequencing technologies offer hope to a large number of patients with cryptogenic encephalopathies and will eventually lead to new therapeutic strategies and more favorable long-term outcomes.

The study reports a girl with pyridoxine-dependent epilepsy. The girl was admitted at the age of 2 years because of intermittent convulsions for 1.5 years and psychomotor retardation. She had a history of "hypoxia" in the neonatal period. At the age of 5 months recurrent epileptic seizures occurred. The child was resistant to antiepileptic drugs, and had many more seizures when she got cold or fever. She also had a lot of convulsive status epilepticus. No discharges were found during several video-EEG monitorings. Cerebral MRI examinations showed normal results. So Dravet syndrome was clinically suspected. ALDH7N1 gene mutation analysis revealed two heterozygote mutations, and pyridoxine-dependent epilepsy was thus confirmed. Seizures were generally controlled after pyridoxine supplementation.

4.Genetic and phenotypic analysis of a patient with phosphogylcerate dehydrogenase deficiency.
Chinese Journal of Medical Genetics 2021;38(2):170-173
OBJECTIVE:
To explore the genetic basis for a child with ocular anomaly, microcephaly, growth retardation and intrauterine growth restriction.
METHODS:
The patient underwent ophthalmologic examinations including anterior segment photography, fundus color photography, and fundus fluorescein angiography. The patient and her parents were subjected to whole exome sequencing. Candidate variants were verified by Sanger sequencing and bioinformatic analysis.
RESULTS:
The patient was found to have bilateral persistent pupillary membrane and coloboma of inferior iris, in addition with macular dysplasia and radial pigmentation near the hemal arch of the temporal retina. She was found to have carried compound heterozygous missense variants of the PHGDH gene, namely c.196G>A and c.1177G>A, which were respectively inherited from her father and mother. Bioinformatic analysis suggested both variants to be pathogenic.
CONCLUSION
The patient was diagnosed with phosphoglycerate dehydrogenase deficiency. Above finding has enriched the phenotypic spectrum of the disease with ocular manifestations.

A boy was admitted at the age of 17 months. He had psychomotor retardation in early infancy. Physical examination revealed microcephalus, unusual facies, and a single palmar crease on his right hand, as well as muscle hypotonia in the extremities and hyperextension of the bilateral shoulder and hip joints. Genetic detection identified two pathogenic compound heterozygous mutations, c.8868-1G>A (splicing) and c.11624_11625del (p.V3875Afs*10), in the VPS13B gene, and thus the boy was diagnosed with Cohen syndrome. Cohen syndrome is a rare autosomal recessive disorder caused by the VPS13B gene mutations and has complex clinical manifestations. Its clinical features include microcephalus, unusual facies, neutropenia, and joint hyperextension. VPS13B gene detection helps to make a confirmed diagnosis.
