“…The only postictal visual phenomena reported is transient postictal blindness, which is a rare phenomenon seen mostly in children and may be related to the relative electrical instability of the occipital cerebral cortex [2]. It has been observed a rare transient adverse effect immediately after ECT [3] and general anaesthesia. Antiepileptic drugs are known to result in visual disturbances, particularly colour vision defects [4].…”

Shocking colours - ECT temporarily improves colour perception in a colour-blind patient

Electroconvulsive therapy (ECT) is often the last resort in medically treatment-resistant patients. The mechanisms of its efficacy are still somewhat poorly understood. However, it is clearly a highly effective treatment for severe and psychotic depression, as well as other severe neuropsychiatric conditions [1]. This case-report attempts to offer a perspective on the impact of ECT on sensorial perceptions, transgressing the well-described cognitive effects. CaseA 30-year-old woman was hospitalised due to moderate depression with suicidal ideation (Hamilton Depression Scale 17-items: 21) six months after the birth of her first child. Treatment with 75mg venlafaxine was inadequate; the depression rapidly worsened during hospitalisation, and 10mg olanzapine was added due to psychotic symptoms. She consented to ECT.She is red-green colour-blind (deutan) as her father and all her mother's brothers. After a few ECT treatments, she experienced seeing new colours e.g. during a walk in the hospital gardens, being able to see the red berries in the fall foliage and in the watercolour paintings she herself had previously done. She reported better colour discrimination and that all colours seemed stronger and brighter during the hours following ECT. However, her vision would be back to habitual state the following morning.Since we have not been able to find reports of improvements in colour perception following ECT or other forms of brain stimulation in previous literature, we performed an Ishihara colour blind test before and after ECT. All 38 Ishihara colour plates (Handaya, Japan) were presented 75 cm away under a 6500K lamp (A60, LIFX, Australia). ECT was administered with bitemporal electrode placement, dose titration ½ of age, pulse width of 0.5e1.0msec, stimulus duration of 6e8sec, a 30e70Hz frequency, and with thiopental anaesthesia.

“…[2][3][4] All 3 of these cases involved individuals younger than 30 years old, and post-ECT neuroimaging did not reveal abnormalities. [2][3][4] Our case presents a different perspective of this rare and unsettling adverse event. Unlike in prior cases, our patient is older, had a past uneventful ECT course, and had associated restricted diffusion in her bilateral occipital lobes on diffusionweighted imaging (DWI) after her ECT.…”

“…T ransient cortical blindness has been reported as a rare neurological sequela of seizures and documented as a rare adverse event occurring after electroconvulsive therapy (ECT). [1][2][3][4] To our knowledge, there are only 3 case reports in the literature of transient blindness immediately after ECT (within minutes to hours) and only 1 report describing continuation of ECT after this adverse event. [2][3][4] All 3 of these cases involved individuals younger than 30 years old, and post-ECT neuroimaging did not reveal abnormalities.…”

On the surface, it seems that ECT had induced severe impairment in spatial cognition and that the impairment showed the familiar pattern of attenuation with the passage of time. However, another recovered patient in the study, who did not receive ECT, also showed substantial spatial deficits on the same subtest of the TPT, and the attenuation of the deficits across time in the ECT-treated patient was probably a result of repeated exposure to the task. We suggest that not all patients who seem to experience spectacular cognitive impairment after ECT have deficits that are attributable to ECT.

Continuation of ECT After Recovery From Transient, ECT-Induced, Postictal Cortical Blindness

Abstract: Patients who experience transient, ECT-induced, postictal cortical blindness may not necessarily experience the same adverse effect on rechallenge with ECT.
