Gadolinium Toxicity Symptoms: What Patients Report
Gadolinium toxicity symptoms can develop after receiving gadolinium-based contrast agents (GBCAs) during an MRI scan. Also referred to as Gadolinium Deposition Disease (GDD), these MRI contrast side effects range from nerve pain and brain fog to skin changes, bone pain, and hair loss. This page presents the most comprehensive published data on gadolinium side effects based on a survey of 316 patients with confirmed gadolinium retention.
As with most medical conditions, the specific symptoms of Gadolinium Toxicity will vary from person to person. Other than what you will read here and in our research papers, there is no published listing of the common symptoms of Gadolinium Toxicity. By means of a symptom survey of 17 people with high urine levels of Gadolinium, we have provided a comprehensive review of this topic in Survey of the Chronic Effects of Retained Gadolinium from Contrast MRIs, which we encourage you to read. On this page, we will provide some high-level information from that paper as well as other observations we have gathered from MRI Gadolinium Support Group. Only collective information is presented. Other than in the Viewpoints section, we will never present individual specific information.
Establishing the Gadolinium Toxicity Connection
Symptoms are generally experienced at an acute level shortly after having a contrast MRI and at a chronic level for years following their last contrast MRI. Some people have the early acute symptoms that they can tie time-wise to their contrast MRI. Often they are very frightened, and any appeals to the medical professionals involved in the contrast ordering or administration process meet with denial or disbelief regarding the connection of their symptoms to the contrast agent, and certainly there is no supportive relief. Others experience chronic symptoms that their doctors cannot explain and through research or testing they make the connection back to their contrast MRI. They, too, are concerned, but more from a viewpoint of "where is all this leading". Many people experience both the early acute problems and the chronic effects. People at both ends of the spectrum want to know what they can do to cure their Gadolinium-related problems. More about that in our Treatment Possibilities section.

Open GAD CheckerKey Findings
Survey Participants
316 patients with normal or near-normal renal function who experienced symptoms after MRI with a GBCA, plus 8 patients with biopsy-confirmed NSF.
Gadolinium Retention Confirmed
185 patients had laboratory tests confirming gadolinium retention 30 days or longer after their last MRI, with some cases showing retention for up to 22 years.
Symptom Overlap with NSF
19 of the 28 most frequently reported symptoms in the NSF Group were also ranked among the top symptoms reported by patients with normal renal function, indicating substantial overlap in clinical presentation.
Nervous System Impact
11 of the 19 most frequently reported symptoms across all patient groups involve the nervous system, consistent with gadolinium's toxic effects on calcium channels.
Unconfounded Cases
75 patients received only one type of GBCA (19 linear & 56 macrocyclic) with confirmed gadolinium retention. The same 14 nervous system symptoms ranked in the top 25 for both linear and macrocyclic agents.
Chronic Effects
43% of patients reported changes in employment status due to health issues, and 41% said altered brain function affects their ability to work as they did prior to MRIs.
