Synapse loss is an early event in the progression of Alzheimer’s disease

Alzheimer’s disease is the most common form of dementia. It is a progressive disease that is characterised by symptoms such as impairments in memory function, language, thought and problem-solving. In the earliest stages of the disease, memory loss is the most commonly reported symptom.

Alzheimer’s disease is characterised by beta-amyloid plaques, neurofibrillary tangles, neurone loss and synapse loss.6-9 Compared with the other hallmarks of Alzheimer’s disease, synapse loss correlates best with impaired memory, and is believed to occur early in the disease process, even before the onset of clinical Alzheimer’s disease symptoms.7-9

Souvenaid (Fortasyn Connect) – formulated to support synapse formation and function5

Synapse formation depends on the production of neuronal membranes, which primarily consist of phospholipids.10-11 Phosphatidylcholine is the most abundant phospholipid in the brain, which is generated primarily via the Kennedy pathway. The production of phospholipids via this pathway is positively affected by the availability of the required nutritional precursors uridine monophosphate, choline and omega 3 fatty polyunsaturated fatty acids.11

Souvenaid (Fortasyn Connect) is the unique combination of these nutritional precursors along with cofactors.5 These components work together to enhance phospholipid synthesis via the Kennedy pathway. The increased phospholipid synthesis supports the formation of neuronal membranes and synapses.11


Souvenaid is supported by 20 years of research1-4

The transition of Souvenaid from research bench to real-world patients is based on decades of research conducted by the MIT and other international institutions.1-4,12-22

Clinical trials have evaluated Souvenaid in early Alzheimer’s disease and demonstrated clinically meaningful benefits for patients.1-4


The first clinical trials with Souvenaid showed encouraging effects on memory performance in patients with mild AD dementia.1,2 Souvenaid was associated with a statistically significant improvement in memory performance in patients with mild and very mild AD dementia, observed over 12 weeks in Souvenir I and 24 weeks in Souvenir II 1,2 and patients continued to exhibit improved memory for up to 48 weeks.23

Based on the results of Souvenir I and II, an independent European Commission funded a new trial focusing on the longer-term use of Souvenaid for memory and cognitive function in the very early stages of Alzheimer’s disease – known as “prodromal AD” or “mild cognitive impairment” (MCI). With patients potentially followed up to 8 years, the LipiDiDiet study is the longest intervention trial in MCI.3

At 3 years the trial concluded that, in people with prodromal Alzheimer’s disease/MCI, the daily consumption of Souvenaid showed significant positive results (slowed decline) in cognitive function, thinking skills, memory, and brain atrophy.3
